  • As for low contrasts and fuzzy edges of infrared images, an infrared image enhancement method combined with adaptive platform histogram equalization and Laplace transformation is pressented to not only improve the image contrasts but also to sharp the image edges. The algorithm uses double Digital Signal Processors(DSP) to complete parallel processing. Among them, a DSP obtains the image contrast enhancement by using the adaptive platform histogram equalization, and the other one performs Laplace transform algorithm to obtain the edge image from an original image. Finally, the multiplied fusion of two images is finished by coefficient superposition. Experimental results show that this algorithm has an excellent enhancement effect and real-time performance, which satisfies the requirement of 50 Hz processing frequency and improves the image contrast and sharps the image edge.
