with you. Please advise me if something is wrong. Assume that our company has two types of programmers: VB programmers, which refer to programmers who write programs using VB, and clsVBProgramer programmers. Delphi programmers refer to programmers who write programs using Delphi, it is represented by the clsDelphiProgramer class. Each class has a WriteCode () method.

Reproduced from: http://www.cnblogs.com/MeteorSeed/archive/2012/08/04/2621993.html A wolf is a real prey in nature, and husky is just a human plaything. The two are indeed very similar, just like the programer and coder in the IT field. If you use Wolf and husky to represent these two occupations, programer is undoubtedly the real wolf in the software industry. 1. Habits of husky They write code that mach

knowledge of image processing, which I am not going to cover in detail here. In addition, compiling this example requires OPENCV, I use the version is 2.3.1, about OPENCV installation and configuration is not introduced here. We first look at the traditional way of serial programming.1 #include "opencv2/highgui/highgui.hpp"2 #include "opencv2/features2d/features2d.hpp"3 #include 4 #include 5 int main () {6 Cv::surffeaturedetector Detector (400);7

other thread is impersonating in it, and if so, wait for the other threads to execute. This avoids the race condition problem, but it is clear that it will be executed at a lower speed because of possible thread waits. (Personal: This uses the same function as the __syncthreads () fence synchronization function in Cuda)With the above basic knowledge, it is enough for me to do a lot of things. Here we look at a specific application, from the hard disk read into two images, the two images extract

Synchronous OMP algorithm, the main idea is: Similar atoms have the same sparse characteristics. Therefore, when sparse representation of similar atoms, assuming that the sparse atom is in the same position, and its selection in the over-complete dictionary of the same atom, the OMP algorithm is the SOMP algorithm in the original signal is an atomThe special circumstances of the time. The OMP algorithm can be unified into the SOMP algorithm, and its solution process is almost the same as the OM

Basic data structures and examples for OPENCVThe strong mat types in the OpenCV are already familiar to us. Here are some of the basic data types that are commonly used in engineering. Including:VecScalarPointSizeRectRotatedrect 1. Vec class 1.1 Basic Concepts Vec is a template class that is used primarily to store numeric vectors. 1.2 usage (1) Accessing VEC vector members using []myvector[0]=0;(2) Use it to define any type of vectorVec(3) The following predefined types can be used typedef vec

LBPV is a var (variance bar), the Var calculation formula:The above GP is the domain pixel value and then normalized.2. PyramidsA total of three levels of pyramid, i0,i1,i2,i0 for the input image, I0 through the Gaussian lowpass filter (Gaussian low pass filter, LPF), and then the next sample to get I1 (sample size 2), also by I1 to get I2,Finally, from bottom to top, each level is extracted in a unified mode LBP, rotation unchanged LBP, uniform rotation of LBP, in the order of the following co

Operation Steps:1. Load images (grayscale or color) and make them consistent in size;2. If the color map, improve the line color space transformation, from RGB to HSV, if the gray-scale map does not need to transform;3. If the histogram is calculated directly, and the histogram is normalized;4. If the color graph, the color histogram is computed, and the color histogram normalization;5. Use similarity formulas, such as correlation coefficients, chi-square, intersections, or babbitt distances, to

, we calculate the probability of each pixel and display it. The output result generated at the appropriate threshold gives us a separate result. Numpy Algorithm 1. First, we need to calculate the color histogram of the object we need to find (Make It 'M') and the image we will search for (Make It 'I '). Import numpy as npimport cv2 as cvfrom matplotlib import pyplot as plt # roi is the object we need to find or region roi = cv.imread('rose_red.png ') hsv =
