Aiming at the problem that difficulty for platform value in measuring image platform histogram equalization, based on the Fuzzy C-means clustering, an adaptive platform histogram equalization enhancement algorithm was proposed. Threshold of the platform is selected adaptively with the algorithm that image histogram Fuzzy C-means clustering. The image can be balanced effectively and the image details can be preserved at the same time. Experimental results show that the measurement image enhancement of the algorithm is excellent and it can suppress the background of the image and highlight the details of the objectives effectively.
