This thesis presents an improved enhancement self-adaptive algorithm based on wavelet decomposition. X-ray digital image are processed by wavelet transformation and reconstruction. Low frequency coefficient fusion can achieve the best fusion effects with less decomposition layers. High frequency coefficient fusion can keep the detail factors of original clear image. All the lab testing results and indicates that the image dynamic ranges are widened and the image contrast level improved highly in the meanwhile.
