to take the local minimum value in the residential area of the source image. Because it is a binarization image, There is only 0 and 255, so a pixel in the residential area is 0 and the pixel is 0, so that the edge of the source image will become 0, to achieve the goal of slimming. Used in opencvcv2.erode()The function performs corrosion by specifying the size of the core: IMG = cv2.imread('j.bmp ', 0) kernel = NP. Ones (5, 5), NP. uint8) Erosion = cv2.erode (IMG, kernel) # Corrosion This core

OpenCV Learning (Pixel operation manipuating the Pixels) OpenCV Although there are many types of image processing functions, you can do a variety of common image processing, but there will always be some operations are not, then we need to manipulate the pixels, to achieve the functions we need. Today we will talk about several methods of OpenCV for pixel-level operation, and make a comparison. In OpenCV, the image is represented by a matrix, and the corresponding data type is

here is the rotation and correction of the human face based on the position of the human eye.The basic ideas are as follows: Rotation correction of the image according to the tilt angle of the two eyes Zoom the picture based on the actual distance in the picture and the custom offset Here is the cut, the final picture is 100*100 pixels, the offset is 0.3Detecting faceCropping Result Its code is: Cv::mat Faceclassifer::cr

The analysis can then be done on a subset, while the other subsets are used for subsequent validation and verification of this analysis. A subset of the beginning is called a training set. Other subsets are referred to as validation sets or test sets.Cross-validation

filter to smooth image processing, the window is placed above the image, through this window to see the image we get.There are many kinds of filters, in OpenCV, we provide the following common image smoothing operation methods and functions:1. Domain mean filter: blur function to replace each pixel of an image with the mean value of the pixels within the adjacent rectangle (mean filter)2. Gaussian low-pass filter: Gaussianblur function3. Box Filter: Boxblur function4. Median Filter: Medianblur

grayscale of each pixel to the average, greater than or equal to the average of 1, and less than the average to 0;5. Calculate the hash value: Combining the results of the previous step, together, constitutes a 64-bit integer, which is the fingerprint of this image. The order of the combinations is not important, just ensure that all images are in the same order;6. After getting the fingerprint, you can compare different images and see how many of the 64 bits are not the same. Theoretically, th

order;6. After getting the fingerprint, you can compare different images and see how many of the 64 bits are not the same. Theoretically, this equates to "Hamming distance" (Hamming distance, in information theory, the Hamming distance between two equal-length strings is the number of different characters in the corresponding position of two strings). If the number of different data bits is not more than 5, it means that two images are very similar, and if they are greater than 10, it means tha
