The ipad user experience is mostly about content and interaction:
Dilute the program UI so that users can focus on what they want.
Beautiful content form, rich sense of reality.
Leverage the performance of the device to enhance the interactivity of the content.

One of the key elements of a good ipad program is that it can be run in all directions. A vertical large s
Image detection is the basis of image segmentation and image recognition, and is also an indispensable key. In the framework of visual computing theory, extracting the basic features of two-dimensional image, such as edge, corner and texture, is the first step of the whole frame. This article has made a detailed theory introduction and related realization to the Harris Corner point algorithm.
Part One : Corner type Introduction
In the real world, corner points correspond to objects ' corners, r

Corner Point: There are two more common definitionsThe corner point is the intersection point of two edges is a feature point with two main directions in the neighborhood (this main direction, in fact, I have been confused, but the reference to the PCA, I think it is in two directions in the gray scale changes relatively large, that is, the point of the corner in the neighborhood, is no longer a two-dimensi

Expressions include: parameter set, lambda operator, function body.
3) Set operators allow you to construct collection types such as set, list, and map.
4) The Java El Streaming API contains filters such as foreach, reduce, filter, map, and so on.
Here you can get a list of collections or lists, call a couple of strings, or run an external filter or aggregate function on the list. For example, you can sum the strings.

One of the properties is that for a certain point, the area centered on him is divided into 8 quadrants, and for each quadrant, only the nearest point-edge is taken. In this case, because the edge is bidirectional, so for each point only need to consider 4 directions, the number of edges is O (4*n), and then u

Vertical display, but based on the device sensor, can either be displayed in normal direction, or reverse display, in the API Level 9 is introduced.
"sensor"
The direction of the display is determined by the direction sensor of the device. The display direction depends on how the user holds the device, and the direction of the display changes when the user rotates the device. However, by default, some devices do not rotate in all four

After the brave fario completed the task, he was quickly retreating to his own base. However, because there is a large group of follow-up troops behind it, fario should return to the base as soon as possible, or else he will be caught by the enemy.
Finally, fario came to the last stop: The field of telachel, where he can return to the base. However, the enemy persists.
the steps are traced back, which leads to many repeated steps.For the second time, I changed BFS, but did not mark the array. Instead, I directly cracked the stack's T_T.The third time is BFS, but a visit [] [] array is added to store the number of steps. In the search process, the number of steps for visit [] [] is updated every time you go to this step, this maximizes the number of remaining steps to the coordinates (x, y.[Cpp]# Include # Include # Include # Include # Include # Include # Incl
