The remote sensing image segmentation is one of key factors, which decide the success of remote sensing image analyze and calculation. Because only if the better segmentation effect is obtained, the follow-up works can be get better effects, such as information extraction and target recognition et al. The background of this paper is high resolution remote sensing image. As these remote sensing images contain a wealth of color, texture and a lot of noise et al, the key point of the research is how to effectively remove noise, smooth the image and reasonably use various information to segment the image. Firstly, the image filtering, color space quantization and spatial segmentation can be completely simultaneously by use the JSEG algorithm, which directly utilize color information. Then, In order to solve the limitation case of the JSEG, such as over segmentation, the improved JSEG algorithm is proposed in this paper. For obtaining the better effect of segmentation, the local J value is corrected by local homogeneous matrix, which gives reasonably description for color homogeneity in region and the boundary of different region. In addition, for weakening or eliminating the over segmentation, the class map is merged by LBP/C operator. It gives stable description for the texture of image. The finally, the evaluation of image segmentation is analyzed and summarized. In addition, the evaluation method of J value and J average value is proposed based on calculating the J value and J average value in JSEG algorithm. The merit is refle
