Because the contrast of the image for guiding the high-speed infrared air-to-air missile is low, its signal to noise ratio is poor and the target and its background gray-scale coupling is strong, the paper analyzes the reasons why the threshold value segmentation method and the fuzzy C-means clustering method have the over-segmentation and under-segmentation in segmenting the above type of image....
Aiming for the feature of low resolution and faint contrast for infrared image, a segmentation algorithm is presented based on the neighborhood weight fuzzy c-means kernel clustering. By using the Gaussian kernel in target function, the traditional euclidean distance in the FCM is replaced by a kernel-induced distance. At the same time, this method computes the sample weight during the clustering...
