3.3 Histogram Processing直方图处理 an image whose pixels tend to occupy the entire range of possible intensity levels and, in addition, tend to be distributed uniformly, will have an appearance of high contrast and will exhibit a large variety of gray tones.一幅图像的像素倾向于占据整个可能的灰度...
Image processing operations implemented with filtering include smoothing, sharpening, and edge enhancement. In image processing applications, filtering is a commonly a neighborhood operation. A neighborhood operation determines the value of any given pixel in the output image by applying some algorithm to...
This paper deals with image processing using spatial (geometric) transforms such as translation, rotation, and scaling, shearing, and projective transform. These transforms can be used for image correction. Translation, rotation, and scaling transform are also called affine transform which is a subset...
