boundary detection Contrast is the difference in luminance or color that makes an object (or its representation in an image or display) distinguishable. In visual perception of the real world, contrast is determined by the difference in the color and brightness of the object and other objects within the same field of view. Because the human visual system is more sensitive to contrast than absolute luminance, we can perceive the world similarly regardless of the huge changes in illumination over the day or place to place. The maximum contrast of an image is the contrast ratio or dynamic range

DOA 中的DML,DML为确定性最大似然算法，具有估计精度高、抗噪性强的优点(In DOA,DML is a deterministic maximum likelihood algorithm, which has the advantages of high estimation accuracy and strong anti-noise)
