Abstract  Based on mean-standard deviation curve descriptor (MSCD),the intensity order mean-standard deviation descriptor (IOMSD) is proposed by introducing the idea of intensity order partition. Different from the fixed-position partitioning used in the construction of traditional descriptors,the sub-regions are partitioned according to the relationship of intensities among sample points. IOMSD overcomes the boundary errors of image deformation,and it is invariant to changes of linear illumination and monotonic intensity. Experimental results show that IOMSD has robust performance under image rotation,viewpoint change and illumination change. Moreover,it is stabler in image deformation than MSCD.
