A Novel Fake Color Scheme Based on Depth Protection for MR Passive/Optical Sensors

Remote sensing image processing is important area in geosciences. Images that are obtained by different types of sensors might be unrecognizable initially or would not contain useful information. To achieve a suitable visual perception of images, series of preprocessing for removing noises and essential corrections and also better analysis of main processes are required, firstly. There are different kinds of processes according to special remotely sensed images. The scheme that we are going to introduce in this article is modified pseudo-color scheme that uses fake colors to colorize the gray-scale images of satellite sensors taken by Landsat8 sensor. A main feature of this method is the original image reversibility that satisfies good resolution of output images and also experimental results show this fact, i.e. happening of intensity/depth protection. In comparison with a fusion-based scheme (HM), similarity of 80% is achieved.
