3. 2 workloads
In the development of the whole program, which mainly in the process of functional editing of the design of each function module, some of the algorithms are more complex, in the design process has some difficulties, in the development of a lot of work load.
3. 4 Personnel
The personnel required to develop, operate, and maintain the software are primarily team members.
3. 5 devices
In the software design process, mainly rely on the team members of their own computer.
3. 6 Limitations
The main limitation of the software is that processing some images will not respond to the time, and in the data storage capacity is insufficient, processing function is not complete. In some of the processing functions of the algorithm because of our team's limited personal capabilities, some of the features of the implementation is relatively imperfect.
4 Recommended Systems
4. 1 description of the proposed system
Because our team is using Windows systems, the development environment is also based on the development of Windows systems. The operation of this software also needs to be run on the Windows system. The basic methods used are to read pictures in the computer, enlarge, reduce, rotate, lasso, move, cover, whitening, freckle and other functions. First, you can run the software, and then read the pictures you need to modify, to lasso, drag the area of interest to move, the area of interest to cover the area of no interest, while reading some images can be tonal adjustment, just move the RGB three-channel proportional size to achieve whitening or freckle effect.

4.3 Where to improve
In the whole software design, some of the functional modules in the algorithm design there are some deficiencies in understanding and understanding, some algorithms due to our team members of the limited personal capabilities, so that there are certain features of some defects, in these aspects of our software there are some improvements.
4.4 Influence
Impact of 4.4.1 on equipment
At present, the main market is the Windows system, but also the Apple system and LINXU system. However, the software we are developing can only be run on Windows systems, and there is a big problem. So that we in the future to improve or expand, to a large extent, the impact of our user volume.
The impact of 4.4.2 on software
In this development, because it is the P diagram of the program development, and the previous computer installed on the PS software has some degree of conflict, occasionally will make the computer crashes, need to restart to normal operation. In this respect is also a big disadvantage, in the late will be slowly modified and improved to achieve compatibility with each software, as well as system compatibility.
Impact of 4.4.3 on user units
Because we are not involved in the use of the relevant units, but only our team members and the vast majority of friends around the use, in the use of attention to our software can not be opened with PS software at the same time, or it will crash, this is also we have not dealt with a bug, but later will be gradually modified, making software compatibility more perfect.
The effect of 4.4.4 on the system operation process
Currently the proposed system is the Windows system, for the user as long as the attention can not be opened at the same time PS and our P-graph software can be run perfectly, but also in the image processing after the save, the current format is mainly Png,jpg,tiff format. Soft once opened the PS software, there is a black screen, force shutdown and then boot can, but just modified the picture is also a night back to liberation, which is our current bug, the latter will achieve real-time saving function.
The impact of 4.4.5 on development
At present, because it can only be run on the Windows system and its development, and can not open the PS software at the same time, otherwise it will cause the computer to crash, and if in the absence of the premise of saving, suddenly shut down or quit the software, for just do all the effort is wasted. In view of the existence of these problems, but also need to consult the expert's guidance, as well as the latter team's gradual groping to improve it. For the security issue, we are holding an open mind to carry out this software development, if interested students can discuss, and work together to join our team, so that the function of the software is more perfect, as far as possible to reduce bugs, perfect operation.
Impact of 4.4.6 on locations and facilities
Because our entire development process is based on the Windows system, and our development site is mainly in the student dormitories and libraries, the location of the requirements have not much impact, in addition to the impact of the facilities, to a certain extent, the destruction of the computer system, so that the team to re-install the system, And the depletion of the CPU in the notebook.
The impact of 4.4.7 on expenses
In the process of software operation, due to the incompatibility with PS, and not automatically save the huge impact, in the late need to maintain and modify, the total cost is 5000 yuan.
4.5 Limitations
The main limitation in this software is that the software is incompatible with similar software on the computer, and it can not be saved automatically after the computer crashes, these problems need to be improved.
4.6 Feasibility of technical conditions
A Although there are some limitations in the current conditions, but still can achieve the target requirements, as long as the start of this software does not start the PS software or in the trial of our development software, the PS software first uninstall.
b In addition, in order to not automatically save the problem, in the process of making changes to ensure that the computer has power, and can not open too much software, and after the image modification and processing for real-time preservation.
C Because the function of the software is now smaller, the personnel required is also less, the current team mainly has two members, and the quality of the existence of some flaws, but the overall view of the implementation of the software is still very high.
5 Alternative system scenarios available
5.1 Selectable System Scenarios 1
The first system is mainly based on the iOS system, the reason why this system became the first choice, mainly our original development is based on iOS system, and the current iOS system is also occupy the majority of the market share, can have a large number of users.
5.2 Selectable System Scenarios 2
The second system is mainly based on Android, because if the software can be applied to the mobile phone, but also a breakthrough progress, and mobile phone users will use more, more to promote the user rate of our software.
6 Investment and Benefit analysis
6.1 Expenditure
6.1.1 Capital Investment
It mainly includes some basic requirements for the software from development to completion, such as:
A. For the cost of housing and facilities, at present, the housing is provided by the school bedroom, 1200 yuan per year, facilities are mainly using notebook computer maintenance, if there is an unexpected need to buy a new computer, the two added together need 9800 yuan. According to the two-year operating period to calculate, a total cost of 15600 yuan.
B. Data management due to the user less, do not need a large number of people to use, so less data storage, no need for large-scale software maintenance, only a 2T of mobile hard disk to achieve data storage, mobile hard disk about 800 yuan.
C. Data communication equipment, mainly the use of Internet access to find information, as well as telephone information and other costs, in total, it will take about 3000 yuan.
D. Security and confidentiality, because we are aiming to improve our hands-on ability and practice, there is no profit and commercialization, so we do not need the maintenance of safety information.
6.1.2 Other Disposable expenses
Due to the small size of the software we have developed and the non-commercial operation, the research and development is mainly our small team, as well as the inquiry fee, travel expenses, inspection fees and so on are personal expenses, not statistics.
6.1.3 Non-disposable expenses
The operating and maintenance costs of the software during the life cycle are mainly the following:
The maintenance cost of the computer should be 2000 yuan altogether;
Personnel are mainly team members, do not need bonuses, spiritual support can be;
Public implementation is mainly the dormitory of the whole electricity and network costs, a total of 4500 yuan;
Other recurring expenses are mainly books and literature download costs, a total of 1000 yuan.
6.2 Benefits
The development of the software p diagram is mainly used by the team and around the vast number of friends, not for commercial use, for free trial, for the later stage of the perfect work to provide users with valuable advice, so no income.
6.2 Sensitivity Analysis
Because we designed the operating cycle of two years, in the case of regular maintenance and two or more times of development, the user will also greatly improve, which will also promote our continued maintenance and to make a higher version of confidence, so the expected operating cycle of 5 years.
7 Feasibility of social factors
7.1 Legal aspects of the feasibility
For the software of the law, at present, does not involve the infringement of this aspect, there may be similar to PS, there is a certain degree of infringement of the patent. However, we are just imitation, and the exercise team in this aspect of the hands-on ability, and other users are only our team and classmates around, but also do not use the software to profit or commercial operation.
7. 2 Feasibility of Use
is still feasible to some extent. Because we are in private, the members of the team and the dorm students have become our original experimenter, it is still possible to achieve the relevant simple P-graph function. However, it cannot be used in a wide range, as the current technology is still immature and needs to be further studied.
8 Conclusion
After a series of analytical studies, as well as an imperfect test, the following conclusions are drawn:
1, also need to the development of software postponed use, because we can not make the form of the app, and can not be uploaded to the Internet for others to download. But to a certain extent, the function of P-graph can be realized.
