image to spectrogram

In the early days, the development tool I used was VB6, and the speed at which VB6 processed images was reflected in my imageshop software. Currently, I have switched to C # To study image algorithms. in C #, there are pointers, which make image processing more efficient. VB. NET used less than half a year at the beginning. Today, I have mastered the situation and made a simple description of VB. NET

Activate jws. mono image processing and jws. mono image processing. I have to say that jws. mono has really brought us great convenience. It saves us time without the trouble of compiling Linux. NET. However, there is no perfect gold, although jws. mono has been able to provide the same effect as our own compilation, but it is still a little inadequate, that is, we cannot use the work related to graphic pro
