  • DCT_JPEG
    给予matlab的JPEG压缩程序,包含原始压缩图片,程序对灰度bmp图片进行JEPG编码,压缩成以0101形式的编码。JPEG编码先把图象色彩RBG变成亮度Y和色度Cr、Cb,它利用人的视觉对色度不敏感的特点,减少一部分色度数据,以达到压缩。 JPEG采取多种编码方式,包含有行程编码(Run Length Coding)和哈夫曼(Huffman)编码,有很高的压缩比。在编码前,先对数据进行分块,离散余弦变换(DCT)及量化,保留能量大的低频信号,丢弃高频信号以达到压缩。(Given to the JPEG compression matlab program, contains the original compressed image, the program of the grayscale bmp picture JEPG encoded, compressed into a 0101 form of encoding. RBG color coded JPEG image into a first luminance Y and chrominance Cr, Cb, which uses the human visual characteristics is not sensitive to the color, reduce the number of color data to achieve compression. Take a variety of JPEG encoding, includes length coding (Run Length Coding) and Huffman (Huffman) coding, a high compression ratio. In the code before the data block, discrete cosine transform (DCT) and quantization, to retain a large low-frequency signal energy, discarding high-frequency signals in order to achieve compression.)

  • ImageRegistration
    基于边缘特征的图像配准算法源码 基于边缘特征的图像配准算法是将不同时间、不同的传感器(成像设备)或不同条件下(天候、照度、摄像位置和角度等)获取的同一场景的两幅或多幅图像根据其边缘特征进行匹配、叠加的处理,最终生成一幅全景图像的方法。该方法具有抗噪性强,匹配速度快,误匹配率低,适用于多种类型的图像等优点,主要可以运用于以下领域: (1)军事研究领域,如飞行器辅助导航系绞、武器投射系统的末制导以及寻地等应用研究; (2)医学图像分析,如数字剪影血管造影DSA血管造影术、肿瘤检测、白内障检测、CT、MRI、 PET、 SPECT图像结构信息融合; (3)模式识别,如特征识别、波形分析、签名证实、目标物运动跟踪、序列图像分析等; (4)计算机视觉,可用于目标定位、自动质量控制等; (5)遥感数据分析,多电磁波段图像信息融合,如多谱段的等场景分类、定位和识别定义好的或已知特征的场景、自然资源监控、核生长监控、市区增长检测等。 本算法实现使用VC++6.0为开发环境,目前只支持灰度图像,感兴趣的朋友可以进一步扩展。(Image registration is a fundamental problem in image processing, which is a process to match two or more images of the same scene taken at different times, from different viewpoints, or by different sensors. Image registration is an important technique for a great variety of applications such as medical image analysis, computer vision, remote image data analysis, image information fusion, and the recovery of the 3–D characteristics of a scene.)
