    In this paper, a road extracting to proposed by combining FLD feature extraction and shape feature. This method has four main steps. Firstly, the color information of labeled the samples is extracted. Then, Fisher linear discriminant is used to implement feature classification to segment the images into two Categories:ro AD and Non-road, according to the information extracted before. After that, the initial road network is extracted by threshold segmentation to the result of according. Finally, the Road shape optimization features and morphological processing are used to remove erroneous extraction and op Timize the extraction results. Experiment results show this proposed method can realize the main road extraction from the remote sensing image with C Olor information.

    I It is proved that image gray level tends to be piecewise constant in the low order partial differ Ential equation denosing model. Considering the applications of wavelet multi-scale decomposition in image processing, a kind of remote sensing image Deno Ising model combining dual tree complex wavelet transform and fouth order partial differential equation are put forward. Firstly, the noise images are multiscalely decomposted by DT-CWT. Then The low frequency components are reserved and noise in high frequency components of other layer are removed by th E Fourth order PDE model. Finally, the high and low frequency components of the the corresponding layer are reconstructed the final IMA Ge. According to the denoising experiments results of the ZY-3 satellite images which have different noise intensities proved that's average PSNR of results by proposed model increases 1~2 DB and the structural similarity increases as. The denoising model proposed can effectively preserve the image details while removing noise.
