number of parameters is the base picture. The second parameter is the folder in which the other images are compared, and the result is a different number of data bits (Hamming distance) between the two pictures.The advantage of such an algorithm is simple high speed, not affected by the size of the picture, the disadvantage is that the content of the picture can not be changed.Suppose you add a few words to the picture, it doesn't recognize it. Therefore, its best use is based on thumbnails. Fi

OIn Digital image processing, there are specific processing algorithms for different image formats. So, before we do the image processing, we need to think about the format of the image we want to design and implementation of the algorithm. Based on this requirement, this paper uses the

The first method: Gaussian template The following text copy of the Let me give you an example of what smoothing is (smoothing), as shown in the following two images: As you can see, Figure 3.2 is softer (and more obscure) than figure 3.1. Does it feel magical. In fact, the implementation is very simple. We add the grayscale of each point in the original image and the gray level of the eight dots around it, then divide by 9, as the grayscale of the c

It is mentioned that obtaining images from cameras/albums is intended for end users. Users can browse and select images as programs. Here, we need to use the UIImagePickerController class to interact with users.To use UIImagePickerController to interact with users, we need to implement two protocols View Code The Code is as follows: # Pragma mark obtains activity images from the user's album -(Void) pickImageFromAlbum { ImagePicker = [[UIImagePickerController alloc] init]; ImagePicker. deleg
