摘要：In this paper, a novel approach is proposed for contrast enhancement of greyscale image using the fuzzy logic based techniques such as contrast intensification (INT) operator. In the proposed algorithm, a measure of contrast of an image is introduced which is maximized to obtain a suitable crossover point for an image. Using this crossover point, the enhanced image is obtained using the INT operator. The image enhancement results obtained are compared with conventional techniques, histogram equalization and adaptive histogram equalization. The index of fuzziness is demonstrated as the performance measure for the enhanced images
