该代码用于图像分类，分割识别。其中包括特征提取。图像处理，把一幅图片中不同类型的水果进行自动分类，识别

本书参考资料为：《 STM32F76xxx 参考手册》和《 Cortex®-M7 内核编程手册》，这两本是 ST 官方的手册，属于精华版，面面俱到，无所不包。限于篇幅问题，本书不可能面面具到，着重框图分析和代码讲解，有关寄存器的详细描述则略过，在学习本书的时候，涉及到寄存器描述部分还请参考这两本手册，这样学习效果会更佳

MOTIVATIONPropeller related acoustic signatures typically exhibit modulationcharacteristics. These modulation characteristics originate from the cavitationprocess that takes place in the water due to the cyclic movement of the propellerThe cavitation process is basically the collapse of air and vapor bubblesdue to variations in the static pressure. These variations in static pressure are aconsequence of the passage of the propeller blades through the water. Thismovement, cyclic in nature, causes amplitude modulation in the static pressureand as a consequence an amplitude-modulated(AM) signal can be detected in areceiverCyclostationary processing techniques have been used to detect andlentify analog and digital communication signals very successfully. Thesetechniques have the advantage of using a more realistic model for the signalthan the stationary model used in most of the more conventional signalprocessing techniquesB BACKGROUNDThe basic elements of cyclic spectral analysis are the time-variant cyclicperiodogram and the time-variant cyclic correlogram. These two functions form aFourier transform pair. This fact is known as the cyclic Wiener relation or thecyclic Wiener-Khinchin relation [Ref. 1: p. 49.1
