实现图像的无损压缩
该程序主要实现图像的无损压缩,具体算法包括:
(1)整数小波变换+SPIHT无损压缩
其中整数小波可以采用JPEG2000提供的5-3小波,也可以采用S+P变换,本程序均已给出。
(2)DPCM+算术编码
DPCM采用的是JPEG中采用的方法;
(3)JPEG-LS标准
JPEG-LS的无损压缩性能非常好,超过JPEG2000。(The program mainly realize lossless image compression, the specific algorithm include: (1) integer wavelet transform SPIHT Integer Wavelet lossless compression which can be used to provide the 5-3 wavelet JPEG2000, can also adopt the S P transform, the procedures are given. (2) DPCM arithmetic coding DPCM is used in JPEG methodology (3) JPEG-LS standard JPEG-LS lossless compression of very good performance, more than JPEG2000.)

现,对细化指纹图像的断裂有很好的修复效果。(The broken ridge fingerprint image processing equipment, image enhancement and other causes will generate pseudo-feature points to be a negative impact on fingerprint identification. While combining the traditional method has the advantage, for the spacing, direction offset small spacing, direction offset large fracture situation, this design window constraints window method and the improved two kinds of constraints, different repair methods. Experimental results show the method to fix a more comprehensive and complete removal of pseudo-feature points, easy to program, well thinned fingerprint image fracture repair.)

DLT-matlab
直接线性变换DLT,直接由像平面坐标到地面空间坐标的直接变换,可用于量测相机,非量测相机(本人用的是 高速相机)。配合前方交会验证l系数的准确与否。以DLT得到的结果为初值,用光束法平差可以期望得到更高精度。是数字摄影测量课程作业的例子。(Direct linear transformation DLT, and the direct conversion of coordinates directly from the image plane to the ground space coordinates, the camera can be used for measuring the non-measurement camera (I use a high-speed camera). Tie the forward intersection verify l coefficient accurate or not. To the the DLT results obtained for the initial value, bundle adjustment can expect greater accuracy. Examples of digital photogrammetry course work.)
