New Algorithm of X-ray Image Enhancement
Wei Li · Modern Electronics Technique · 2010
Since the images produced by the vision system based on X-ray image intensifier often have limitations such as narrow dynamic range,and low contrast,a new X-ray image enhancement algorithm is raised here.Two X-ray images taken at different X-ray tube voltages and currents are fused by digital wavelet transform to expand the dynamic range of the X-ray images,and then adopts the dual-platform histogram equalization algorithm to enhance the fused image.The experimental results show that the X-ray images are enhanced effectively.
