In order to improve the influence of non-uniform illumination and the measurement precision, a novel enhancement algorithm was proposed. Although bad illumination condition infection could be removed by MSR, when used in particle images, contrast enhancement effect was not been satisfactory. Then a non-linear gray transformation was introduced in image contrast extending. The experiments proved that enhanced images processed by the novel algorithm had more uniform background and higher contrast than former enhancement algorithmic. Over enhancement was avoided and it also could improve segmented efficient and ensure accurate segmented results.
