Embodiment Construction
[0032] An embodiment is narrated below in conjunction with accompanying drawing, and the present invention is further described.
[0033] This embodiment is accomplished through the following method steps: image pyramid (funnel-shaped) decomposition, excessive contrast suppression, detail contrast enhancement, edge enhancement, noise suppression, pyramid (bucket-shaped reconstruction), such as figure 1 shown.
[0034] .1 Image pyramid (funnel-shaped) decomposition:
[0035] Using the Laplacian pyramid decomposition transformation, the medical image is decomposed into a pyramid-like bucket arrangement, and the 4096*4096 image is decomposed into 12 layers of resolution images (2 12 =4096), if the image is not square, take the maximum length and width. The image is interlaced and alternated, and the next-level low-resolution image is obtained by sampling. And so on (i=0....L-1). Such as diagram 2-1 However, the difference from pyramid decomposition is that when the image is...
