A Comparative Analysis of Compression Techniques – The Sparse Coding and BWT
No full textAbstractThe process of image compression has been the most researched area for decades. Image compression is a necessity for the transmission of images and the storage of images in an efficient manner. This is because image compression represents image having less correlated pixels, eliminates redundancy and also removes irrelevant pixels. The most commonly known techniques for image compression are JPEG and JPEG 2000. But these two have certain drawbacks and thus various other techniques have been popping up, of late. Recently, a growing interest has been marked for the use of basis selection algorithms for signal approximation and compression. In the recent past, the orthogonal and bi-orthogonal complete dictionaries (like the Discrete Cosine Transform (DCT) or wavelets) have been the dominant transform domain representations. But, the DCT and the wavelet transform techniques experience blocking and ringing artefacts and also these are not capable of capturing directional information. Hence, sparse coding method (by Orthogonal Matching Pursuit (OMP) algorithm) comes into picture. Another, novel technique that has taken up recent interests of the image compression area is the Burrows-Wheeler transform (BWT). BWT is generally applied prior to entropy encoding for a better regularity structure. The paper puts forth the comparison results of the methods of sparse approximation and BWT. The comparison analysis was done using the two techniques on various images, out of which one has been given in the paper
Estimation of genetic and crossbreeding parameters for preweaning traits in German Angus and Simmental beef cattle and the reciprocal crosses
No full textData from pure breeds, as well as reciprocal crosses of German Angus (GA) and Simmental (SIM) beef cattle, were used to estimate genetic parameters and to evaluate the suitability for crossbreeding in terms of increasing productivity. Traits of interest were calving difficulty, birth weight (BWT), weaning weight (WWT), and ADG from birth to weaning. Data were collected over a period of 7 yr from 1997 and 1998 until 2003 and 2004, whereas crossbreeding was carried out in 2002 and 2003, and 2003 and 2004 only. Variance components and differences between breeds, individual heterosis, and maternal breed effects were analyzed based on 1,441 purebred and 329 crossbred records for BWT and 1,319 purebred and 316 crossbred records for WWT and ADG, respectively. Mean calving difficulty scores were greater in SIM than in GA ( P < 0.001). For BWT, WWT, and ADG both reciprocal crosses fell between the purebreds, and for all 3 traits SIM showed greater average values compared with GA. The estimated heritabilities were 0.23 for BWT and 0.12 for WWT. Values for the maternal effect and the correlation between additive and maternal effect were 0.18 for BWT, 0.08 for WWT, 0.32 for BWT, and 0.50 for WWT, respectively. Individual heterosis was only significant for BWT (3.7%; P < 0.01). Superior mothering ability of SIM was implicated by greater WWT and ADG of SIM as dam against the reciprocal cross ( P < 0.001). The results provide information about the extent of individual heterosis and maternal breed effects.German Research Foundation [DFG-SFB 299
