First, the basic form of image operation
Forward reverse scan scan
1, point operation
In the processing of each pixel of the image, the operation that only inputs the pixel gray level is called point operation.
2. Domain operations
In the processing of each pixel of the image, not only input the gray of the pixel itself, but also input some pixels in the local region of the pixel as the center of the operation, called puting.
3 、 parallel operation
puting is the same processing operation on each pixel of the image.
The point operations are independent of other pixels because the results are the same regardless of the results of forward scan or reverse scan, so the parallel operation can be used in point operations.
For field operations, you can use of puting. The treatment used pretreatment results, so we can not use parallel processing methods.
4. Serial operation
According to order of pixel by pixel processing method. Here's the picture.
5, iterative operation
Repeat the same process operations, called iterative operation.
6. Window operation
In order to reduce putation time of the image, often a part of the ope
