    摘要: A method of blending a pair of images, each image comprising a plurality of pixels having an intensity. A blending edge is determined for each image, each blending edge comprising at least one group of pixels, with each pixel at a pixel position, and an average intensity of pixels of the blending edges is determined at each pixel position. The method includes determining a scaling factor based on a relationship between the average intensity and the intensity of the pixel of the at least one group of pixels of the blending edge at each pixel position of each image. A blending area is determined for each image, each blending area comprising at least one group of pixels having a pixel at each of the pixel positions. The intensity of the pixel at each pixel position of the at least one group of pixels of the blending area of each image is scaled with the corresponding scaling factor.

    摘要: A method of intensity correction of at least two frames, each frame comprising a sequence of at least two images, each image at a different image position in the sequence and each pair of adjacent images having an overlap region. The method includes selecting an image at a same image position in each frame as a reference image. A set of global intensity transformations is determined, one global intensity transformation for all pairs of adjacent images at corresponding pairs of adjacent images positions of all frames, wherein the global intensity transformations are relative to the reference images. Each global intensity transformation is applied to each pixel of one image at each corresponding pair of adjacent image positions.

    摘要: A method and system for blending images into a single image. Initially two images of a view are selected, wherein the images have overlapping content of the view. The images can differ from each other in such characteristics as time, camera location, camera settings, and lighting. The images are divided into strips along a common plane in a region of each image where the images overlap. A strip from each image is selected where the images are a close match. Pixel by pixel difference values between the two strips are calculated, and a cut line is determined where the differences between the two strips are minimized. Each image is cut along the corresponding cut line, and the cut images are blended together to form a single image of the view. The blended single image can be further processed by warping the image along the cut line to provide for a smoother fit between the two images.

    摘要: A color image processing method and apparatus thereof are provided. The color image processing method includes the steps of (a) sorting image pixels according to the color distance between the image pixels and a central pixel, (b) grouping the sorted pixels into groups in which the difference in the intragroup color distance is minimum and the difference in the intergroup color difference is maximum, and (c) performing filtering by replacing a central pixel value with a predetermined pixel value determined by pixel values of pixels in the groups. The color image processing method can reduce the generation of edge blurring of the image in removing impulse noise from an image and filtering the same.
