人体脑图像分割技术研究a. 对原始的二维医学图像进行滤波,封装成三维体数据。
b. 采用合适的多阈值分割方法得到合适的双阈值,对三维体数据进行二值处理,得到分割出的三维人脑图像。
c. 对得到的三维人脑二值图像进行数学形态学操作,并利用种子填充进行区域修整,得到较好的三维人脑分割结果,并给以三维显示。

CBIR
一个基于Gabor滤波器组的多特征融合的图像检索算法(CBIR based on Multi-Features Combining Multi-parameters from Gabor Filter-bank, 简称multi法),融合了基于Gabor 小波系数的标准方差,峰态,能量,平滑度和一致性度量五个特征量度,实验表明,该算法是一种更加有效的图像检索方法。(we propose a CBIR algorithm based on Multi-Features Combining Multi-parameters from Gabor Filter-bank(called multi algorithm for short), which use Gabor filter banks and combine five features including standard deviation, kurtosis, energy, smoothness and uniformity together. The results of experiments show that this algorithm is a more effective method used for image retrieval.)

DCTJPEG
blkproc.m,DCHuffmanEncoding.m,ACHuffmanEncoding.m,zigzag.m,PSNR.m,
对灰度图像进行DCT变换,量化,ZigZag扫描,Huffman编解码,反量化,反DCT变换而重建图像。
其中,blkproc.m为分块DCT变换函数;
DCHuffmanEncoding.m,ACHuffmanEncoding.m分别为DC和AC变换系数的Huffman码表函数;
zigzag.m为ZigZag扫描函数;PSNR.m为求图像峰值信噪比函数。

Undecimated-DWT
对Lena图先进行jpeg压缩,再对压缩后的图像分别进行小波软阈值去噪和非抽样硬阈值去噪,比较两种去噪方案,非抽样硬阈值有更好的效果。这是根据一篇外文文献来进行编程的,最后有图像对比结果。(According to the paper of OPTIMAL WAVELET THRESHOLDING FOR VARIOUS CODING SCHEMES ,I firstly compresse the Lena picture using the jpeg method ,then respectivly denoise it using the wavelet soft-thresholding method and the undecimated DWT hard-thresholding method.Comparing the two method ,we can find the undecimated DWT hard-thresholding have a better result.)
