### MATLABImageProcessing: Meaning of false rejection rate, false recognition rate, calculation and other error rate Matlab source code (Network First)

The error rejection rate and false recognition rate are two concepts in image processing. The false rejection rate refers to the error rejection, which refers to intra-class matching. If there are 10 samples of volunteers, each of them has 20 samples. Then, compared with in-class tests, for example, the 20 images in the same category of volunteers on the first day can be matched with each other. Assuming th

### MATLAB exercise program (Border Processing for image filtering)

When writing a filter program, we generally use a matrix template to perform convolution with the original image. At this time, when processing the image boundary, we generally choose to ignore the edge, but if the template is relatively large, so the processing effect is not good, the

### Two methods of batch processingimage in MATLAB

There are basically two methods: one is to unify your image once to rename such as: 1.jpg,2.jpg and so on, and then use the For loop in order to process it, such as the following statement: Imagine your image has 20 pairs: Str= ' d:\ do bad \ good image \ '; % of my images placed in D disk, do the poor folder under the Good i
