[0015] In order to describe in detail the technical content, structural features, achieved objectives and effects of the present invention, the following is a detailed description in conjunction with the embodiments and accompanying drawings.
[0016] See figure 1 , The embodiment of the method for realizing GPU operation to improve DR image processing speed in the present invention mainly includes the steps:
[0017] Step 101: Read the original medical image data, and use the edge pixels of the image to expand and complement the original medical image, where the original image size is imageW×imageH, and the convolution kernel size is kernelW×kernelH. The image size is fftW×fftH, where fftW=imageW+kernelW-1, fftH=imageH+kernelH-1;
[0018] Step 102: The fast Fourier transform FFT program written by the CUDA computing unified device architecture programming model directly calls the computing resources of the GPU, and performs FFT operations on the expanded and supplemented original m...
