coherence_enhancing_diff
coherence_enhancing_diff
* This example program shows how coherence_enhancing_diff can be used
* to enhance a fingerprint image by joining disconnected parts of the
* fingerprint lines.
read_image (Image, 'fingerprint')
get_image_size (Image, Width, Height)
dev_close_window ()
dev_open_window (0, 0, Width * 2, Height * 2, 'black', WindowHandle)
dev_display (Image)
stop ()
* Image 是输入图像 ImageCED 是输出图像，0.5是sigma,平滑的尺度；4是rho,扩散系数；0.5是时间间隔；50是迭代次数
