power law transformation of an image

简单的GUI 读人界面，实现图像的灰度反转，对数及幂次变换已经直方图均衡,而且借助sobel算法实现锐化功能-Simple GUI interface to read people, to achieve gray-scale image inversion, logarithmic and power law transformation has been histogram equalization, and sharpening algorithm using sobel function

1.先用LAPLACIAN进行增强 2.用SOBLE进行边缘增强 3.然后将LAPLACIAN*SOBLE SMOOTH 4.将MULTILITION+原图 5.最后对图形进行power-law transformation -1 LAPLACIAN carried enhanced. Edge enhancement using SOBLE 3. Then Laplacian.* SOBLE the SMOOTH 4. MULTILITION+ artwork 5. Fin

利用对数变换进行图像变换 公式：x1=c*log(double(x)+1)(1.Image Enhancement Using Intensity Transformations The focus of this project is to experiment with intensity transformations to enhance an image. Download Fig. 3.8(a) and enhance it using (a) The log t
