This e-book constitutes the referred lawsuits of the eighth China convention on photo and photographs applied sciences and functions, IGTA 2014, held in Beijing, China, in June 2014. The 39 papers provided have been rigorously reviewed and chosen from one hundred ten submissions. They disguise quite a few points of analysis in photograph processing and photographs and similar issues, together with item detection, trend acceptance, item monitoring, type, snapshot segmentation, reconstruction, etc.

Example text

The PCT is applied to a rectangular area called a macroblock. A transform called photo overlap transform (POT) is used with the PCT to eliminate the artifacts in the boundary between blocks. 2 Next, the transformed coefficients are quantized. Quantization parameters (QP) give a great impact on the image quality. After the coefficient prediction, an adaptive scanning is processed and coefficients are rearranged from two-dimensional form to one dimensional form. Finally, the scanned coefficients are entropy coded using adaptive Huffman tables.

Gradient-Based Multi-resolution Image Fusion. IEEE Transactions on Image Processing 3, 228–236 (2004) 18. : Image fusion by using steerable pyramid. Pattern Recognition Letters 22, 929–939 (2001) 19. : Multifocus image fusion using region segmentation and spatial frequency. com Abstract. Lossless or near-lossless compression for high resolution image is required to meet the increasingly high quality demands in various application fields. With respect to this requirement, ultra-high definition image/video compression technology is researched in this papar.

2 Predicted Generator Module According to the fundamentals of intra prediction, it is proved that there are many common calculation parameters for different prediction modes, and many calculation formulas can be achieved in a same configurable calculation unit. In conclusion, we can obtain a configurable architecture for prediction generator module, and the processing element (PE) array is designed to generate concurrently 16 prediction pixels as shown in figure3. (1) Parallel processing unit Considering the clock frequency and the effective use of middle result registers, we proposed a parallel configurable and pipelining processing units to achieve the prediction calculation.
