灰度图像的位面图程序 matlab环境下写的 希望能有帮助(Gray image Bit plane map program, hopes to help you)

求解带可变权值的最短路径问题，如铁路、公路不同的路段组合运输费问题。注：公路的运输费用与路长成正比，铁路的运输费与路段的累积有关等等(Solving the shortest path variable weight problems, such as railway, road sections of different combination of transportation charges. Note: The cost of road transport and road length is proportional to the railway and road transport costs, etc. related to the cumulative)

contrast adjusment 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
