Abstract

A real-time color transfer system based on 3 pieces of multi-media DSP TM1300 for low-light level visible(LLLV) and infrared(IR) images is built. Computing quantity is split among three TM13003. Two pieces of TM 1300 preprocess the dual-band images and calculate their mean and standard deviation respectively. The third TM1300 executes fusion and color transfer in YUV space: Firstly the two preprocessed images are fused into one primary color image(source image) in which hot targets present warm color, cold targets present cool color. Then the mean and standard deviation of source images in Y, U, V components are deduced by preprocessed images pixel value and their mean and standard deviation. Finally, the Y, U and V component of source image are scale by the variation ratio of a day-time color image(target image) to the source image. The color and luminance distribution of the target image is transferred into source image and makes it present a sort of day-time color appearance. Comparing to the usually used lαβ space, color transfer in YUV space can avoid iterative color space transformation, logarithmic and exponential calculation, and thus be effective in real-time realization while the color transferred results are acceptable.
