By the preprocessing method of the integration with the median filter and the linear transform of gray value, and the evaluation function based on power spectrum, an auto-focusing model is built. From the character of the image focusing algorithm based on power spectrum, the paper has designed the structural frame and algorithm flow of the image processing module, and proposed the pipelining structure,...
According to the research of the image focusing model based on Power Spectrum, this paper puts forward the implementation of an auto-focusing system based on FPGA, mainly including image preprocessing, definition evaluation and focusing control. Considering the computational complexity of the auto-focusing algorithms, a series of methods are used. That is, the image preprocessing method of combining...
