Polarization image color fusion method based on YUV space

Based on the characteristics that human eyes are sensitive to brightness and color, a polarization image color fusion method of YUV space is proposed. The brightness information of visible image and various polarization information of polarization image are fused in the YUV space, and the polarization property of targets displayed in the form of color difference in the resulting fused color image. So the polarization visualization is realized and meanwhile 'untrue' colors of mapping polarization information into pseudo-colors are avoided. The fusion results show that the resulting images have higher information content than each of the original images, that are more suitable for the observation characteristic of human eyes and can enhance the perceptual conception to target property. The fused results of independent degree of linear polarization image and independent polarization angle image appear better than others.
