Description: 针对FCM算法的运行时间长和计算量大的问题，提出了改进的FCM算法，先将图像分割成窗口大小的子块，然后以子块为单位提取特征向量，用FCM聚类粗分割，然后对边缘子块，以像素为单位从新提取特征向量，进行细分割。分割后的结果提高了运行速度和分割精度。-For the FCM algorithm and the calculation of long run the problem of large proposed improved FCM algorithm, first image into blocks the size of the window, and then sub-block feature vector extraction unit, using FCM clustering coarse partition, and then block on the edge, in pixels from the new Feature Extraction, for fine segmentation. Improve the segmentation results after the speed and accuracy of segmentation. Platform: |

Description: iii) Discrete Cosine Transform
The transform of a signal is just another form of representing the signal. It does not change the information content present in the signal. Discrete cosine transform is widely used in image and video compression applications such as JPEG and MPEG. These multimedia standards partition an input image into 8 × 8 blocks after that the DCT for each block is computed. Platform: |
