Description: JPEG压缩算法的核心是“视觉保真”原理，利用人类视觉系统特征进行处理，以达到最大图像数据压缩效果，实际上就是去除那些人眼不易觉察的信息。图像的空间频率对人的视觉至关重要，采用离散余弦变换可将图像分解成一组波，每个波有一个不同的空间频率，这样可以去除人类眼睛觉察不到的信息，而且还可使系统只保留重要的信息。-JPEG compression algorithm is the core of " visual fidelity" principle, the use of the characteristics of human visual system to deal with in order to achieve the greatest effect of the image data compression is actually not easy to remove the eyes of those who perceived the information. Image spatial frequency is essential to human vision, the use of discrete cosine transform image can be broken down into a set of waves, each wave has a different spatial frequency, so aware of the human eye can not see the removal of information, but also to make system, only the important information.

Description: Lossless image compression plays a very important role in image processing. However, it develops very slowly and it is difficult to improve the efficiency of compression, since complete information and high fidelity are demanded. The lossless compression ratio of the conventional methods is around 2:1 and 3:1, which doesn’t satisfy practical compression needs. So, it is necessary to develop more efficient lossless image compression methods.

Description: Total Variation Denoising-TV denoising (scalar fidelity term) [ROF92]
Reduces the total-variation of the image. Filters out noise while preserving edges. Textures and fine-scale details are also removed. In this demo the assumption is that a white Gaussian noise is added with a-priori known (or estimated) noise power (variance). The fidelity term to the input image is calculated automatically so that the power of the noise is reduced.

Description: Abstract—Constraining by cameras’ view-angles of the
outdoor monitoring systems, the panoramic digital images
fail to be obtained directly from photographing. A method is
proposed on the basis of the scale invariance feature
transform (i.e. SIFT) algorithm to stitch images captured by
the turning video cameras together to form panoramic
images. Based on the SIFT features and the retrofitted KD-
Tree structure, the BBF searching strategy is employed to
match feature points. Then in a post-processing pass, the
Ransac algorithm is adopted to remove the mismatching
feature points. Photos captured by a surveillance camera are
taken as the input to test the proposed method. According to
the test, the whole processing time of stitch is reduced while
the fidelity of resulting stitched panoramic images is
ensured.-Abstract—Constraining by cameras’ view-angles of the
