【source in ebook】 facedetection DL : 0: Abstract—In this paper, a new lossy technique based on wavelet transform for compression of breast ultrasound images is presented. The experiments are performed on 16 different wavelet functions and the quality of reconstructed images is evaluated by using Compression Ratio (CR), Normalized Mean Square Error (NMSE), Normalized Absolute Error (NAE), and Peak Signal to Noise Ratio (PSNR) criterion. An ultrasonographer performed the subjective assessment. This study shows that among the utilized wavelets,

【Audio program】 Fast-Block-Matching DL : 0: 为提高基于块的运动预测的搜索精度,该文基于块匹配准则,提出最小绝对差分误差和(SADD)算法。SADD 以 SAD 为基础,利用块匹配中相邻像素点误差之间相关性,将块内各像素误差按一定顺序进行差分,消除了相邻点误差之间的冗余。该算法更精确地表达了块与快之间的相似程度。实验结果表明,该算法可有效降低码率,提高 PSNR 值,而且其鲁棒性好,可适用于各种序列。 -n order to improve the search accuracy performance of motion estimation based on block, this paper researches the block matching algorithm, brings forward a new matching algorithm named the minimum Sum Of Absolute Different Differences(SADD). Based on SAD, the algorithm SADD takes advantage of the relativity in the adjacent differences inside one block, adopts the difference operation in a certain order to remove the redundancy, which enables the algorithm SADD to describe the similarity between two blocks much more accurately. Simulation result shows that this algorithm can reduce the bitrate effectively and improve the PSNR performance well. And it can be adapted to kinds of video sequences.

【source in ebook】 NCAET_EC_39 DL : 0: In Medical digital images, produced by various imaging devices like x-ray, CT, magnetic resonance imaging (MRI), ultrasound, etc., use for diagnosis of diseases. Ultrasonic imaging is a widely used medical imaging procedure because it is economical, comparatively safe. The main problem during diagnosis is the distortion. These distortions are termed as ‘Noise’. This study focus on one type noise, namely, ‘Speckle Noise’, produced by ultrasonic devices. This paper concentrated to reduce speckle noise and the studies the effect of different filtering techniques for speckle reduction. The paper introduces the speckle reducing anisotropic diffusion (SRAD) method that reduces the noise effectively without loss of original image. The experimental results proved that SRAD gives higher PSNR. The performance of SRAD was superior compared to traditional lee, frost, kaun filter.
