Remote-Sensing-Image-Processing
基于偏微分方程的遥感图像处理方法 利用测试图像对算法进行仿真验证,并与其它图像去噪算法进行去噪效果比较,通过数值对降噪效果进行评估,得出该方法不仅能够去除噪声而且能够很好的保护图像的边缘等细节信息,弥补了高阶非线性扩散去噪方法导致边界模糊的缺陷,提高了遥感图像的质量,改善了视觉效果(Simulation algorithm of remote sensing image processing methods based on partial differential equations using the test image denoising results compare with other image denoising algorithm to assess the value of the noise reduction effect, draw the method can not only remove the noise but well protected image edge details, to make up for the higher order nonlinear diffusion denoising method lead to fuzzy boundaries defects and improve the quality of remote sensing images and improve the visual effects)

Image segmentation systems have the potential to dramatically improve the performance of Digital image processing. Segmentation procedures partition an image into its constituent parts or objects. In general, segmentation is one of the most difficult tasks in digital image processing. Detection of salient image regions is useful for applications like image segmentation, adaptive compression, and region-based image retrieval. This problem can be tackled by mapping the pixels into various feature spaces, which are subjected to various grouping algorithms It present a novel method to determine salient regions in images using low-level features of luminance and color. The method is fast, easy to implement and generates high quality saliency maps of the same size and resolution as the input image.

dirty glass
建立一个透明物体上有污点的模型,可以模拟玻璃上有污点的图象(Rendering of clean transparent objects has been well studied in computer graphics. However, real-world transparent
objects are seldom clean—their surfaces have a variety of contaminants such as dust, dirt, and lipids. These
contaminants produce a number of complex volumetric scattering effects that must be taken into account when
creating photorealistic renderings. In this paper, we take a step toward modeling and rendering these effects. We
make the assumption that the contaminant is an optically thin layer and construct an analytic model following
results in radiative transport theory and computer graphics. Moreover, the spatial textures created by the different
types of contamination are also important in achieving visual realism. To this end, we measure the spatially
varying thicknesses and the scattering parameters of a number of glass panes with various types of dust, dirt, and
lipids. We also develop a simple interactive synthesis tool to create novel instances of the me)
