The invention provides an image processing method and system. The method comprises the following steps: determining a binary image containing edge feature information of an original image; mapping thereduced image to an original image; for each reduced pixel point, based on the binarized image, determining the number of edge pixel points in N original pixel points closest to the reduced pixel point; according to the number of the edge pixel points, carrying out weighted calculation on the original pixel values of the N original pixel points by adopting the corresponding weights to obtain reduced pixel values of the reduced pixel points; and determining reduced pixel values of all reduced pixel points in the reduced image. In the scheme, the binarized image is generated by using the edge information of the original image, and the corresponding weight is selected to carry out weighted calculation on the N original pixel points according to the number of the edge pixel points in the N original pixel points closest to the reduced pixel points so as to determine the reduced pixel values of all the reduced pixel points in the reduced image. Image reduction is performed by combining theposition information and the edge information of the original image, so that the image information storage rate is improved.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and system. Background technique [0002] With the development of science and technology, images have become more common things in daily life and work. A more common processing method when processing images is to reduce the image to a preset size to meet specific needs. [0003] At present, the multi-phase bicubic algorithm is usually used to reduce the original image. The specific reduction method is: map the reduced image space to the original image, and use the weighted average to calculate the reduced image according to the relative position between the reduced image and the original image. pixel value. However, the existing image reduction method only completes the image reduction according to the spatial position information of the image, without considering the content information of the image, and it is easy to cause problems ...
