Description: This program is the haar opencv face detector slightly modified for ease of use
There are command line options available to avoid the need to use the gui (see
facedetect.cpp for the command line option format
This program needs fltk installed. It can be downloaded online.
The standard facedetect.cpp works at one scale. Our facedetect pyarmids the
image up and down to allow processing at more scales. This can also be
achieved via the cvHaarDetectObjects function.
This program has only been tested with uncompressed avi files Platform: |

Description: 一種基于塊樹結構的SPIHT數字圖像壓縮算法: 在分析圖像經過小波變換后所具有的特性的基礎上,提出了一種改進的SPIHT算法.由于低頻系數占據圖像的百分之九十以上的能量,在圖像的重構中十分重要,所以,對這些系數不進行壓縮而直接傳輸 而最高頻系數相對不重要,所以不做處理,只在圖像重構時以指定的數值予以重構,因此不僅提高了圖像的質量,同時提高了圖像的壓縮率.在具體的算法中,提出了塊樹的結構,減少了算法所需的內存,拓寬了算法的應用范圍.-A tree structure based on the SPIHT block of digital image compression algorithm: After the analysis of images after the wavelet transform features, based on a modified SPIHT algorithm. Due to the low frequency coefficient images occupy more than 90 percent of energy in image reconstruction is very important, so these factors do not directly transfer compression The most high-frequency coefficient is relatively unimportant, so no treatment, only when the image reconstruction be designated numerical reconstruction therefore not only improve the image quality, while improving the image compression ratio. algorithms in specific, the proposed block-tree structure, the algorithm to reduce memory requirements and broaden the scope of application of the algorithm.

Description: technique is quite small owing to the low compression ratio. Based on this, a general least significant
bit-plane (LSB) embedding technique in the spatial domain was proposed by Celik et al. [6]. The payload and
imperceptibility of embedded data are largely improved because of the more efficient compression technique.
Domingo-Ferrer et al. [5] proposed a spread spectrum data hiding method that is only reversible with respect
to the modified version of the original host signal . Xuan et al. [7] proposed a reversible data hiding algorithm
