A broad doming of the Gulf coastal 250 m in thickness [Fisk and MacFarlan, 1955]. It plain between Jackson, Mississippi, and New is not clear how movement on the east-west Orleans, Louisiana is indicated by leveling trending slump faults, which cut the coastal surveys carried out in 1934, 1959, 1964, and plain, contributes to regional subsidence. These 1969. The progressive arching over a distance of faults, initially formed during deltaic 275 km attains a maximum average rate of 3.4_+0.5 deposition, result from differential compaction mm/yr relative to Jackson. Additional leveling in [Cloos, 1968] and gravitational instability

In order to restore image color and enhance contrast of remote sensing image without suffering from color cast and insufficient detail enhancement, a novel improved multi-scale retinex with color restoration (MSRCR) image enhancement algorithm based on Gaussian filtering and guided filtering was proposed in this paper. Firstly, multi-scale Gaussian filtering functions were used to deal with the original image to obtain the rough illumination components. Secondly, accurate illumination components were acquired by using the guided filtering functions. Then, combining with four-direction Sobel edge detector, a self-adaptive weight selection nonlinear image enhancement was carried out. Finally, a series of evaluate metrics such as mean, MSE, PSNR, contrast and information entropy were used to assess the enhancement algorithm. The results showed that the proposed algorithm can suppress effectively noise interference, enhance the image quality and restore image color effectively.
