METHOD AND APPARATUS FOR ENHANCING RESOLUTION BY NEAREST NEIGHBOR CLASSIFIED FILTERING, AND COMPUTER READABLE MEDIUM HAVING INSTRUCTIONS TO ENHANCE RESOLUTION BY NEAREST NEIGHBOR CLASSIFIED FILTERING

摘要

plurality of spatial class (spatial class) from the input image vector to the nearest adjacent to the class determined by image Method for improving the resolution and apparatus is disclosed. In one embodiment, the closest adjacent first class is determined by receiving the input image vector to be classified in one of several spatial class (305). Each class has a normalized average space class corresponding vector. Input image vector is normalized (310). After that is the weighted distance to each vector of normalized average class determined from the normalized image vector, 320. The closest adjacent class is a class for the input image vector is determined based on a weighted distance 330. Is closest to the filter is applied to the class corresponding to the neighboring input image vector to improve the resolution of the image (340).
