| 20090010557 | METHOD AND APPARATUS FOR REALIZING ADAPTIVE QUANTIZATION IN PROCESS OF IMAGE CODING - A method and apparatus for realizing adaptive quantization in the process of image/video coding, which includes the following steps: acquiring the parameter information of the neighbor blocks of the current block; determining the quantization mode of the current block according to the parameter information of the neighbor blocks; and performing quantization processing on transform coefficients of the current block by using the determined quantization mode. Wherein, block coding type and motion vector of the neighbor blocks are used as the parameter information for determining the quantization mode of the current block. An apparatus for adaptive quantization in process of image/video coding is provided. The invention can use different quantization mode for adaptive quantization in different image content of an image sequence, thereby improving the subjective quality of the compressed images at the same bit rate. | 01-08-2009 |
| 20090034612 | QUANTIZATION METHOD AND APPARATUS IN ENCODING/DECODING - A method and apparatus is provided for implementing quantization in encoding/decoding. Firstly, the quantization on the picture transformed coefficient matrix is performed using a quantization parameter model, that is, the coefficient matrix is modeled as a parameter model represented by only several parameters, in which the parameter model includes two sorts of parameters, frequency band distribution parameters and frequency band weighting parameters. Thus, a quantization matrix conforming to the human vision system can be obtained by controlling the model parameters and the subjective quality of the encoded picture can be easily controlled. Secondly, the method does not need to store or transfer the quantization matrix in the bitstream which help to improve the encoding efficiency. Finally, the quantization on picture transformed coefficients using the method is well adapted to the content information of the picture to be encoded. Therefore, the present invention can improve the subjective quality of the encoded picture. | 02-05-2009 |

| 20090080695 | Electro-optical Foveated Imaging and Tracking System - Conventional electro-optical imaging systems can not achieve wide field of view (FOV) and high spatial resolution imaging simultaneously due to format size limitations of image sensor arrays. To implement wide field of regard imaging with high resolution, mechanical scanning mechanisms are typically used. Still, sensor data processing and communication speed is constrained due to large amount of data if large format image sensor arrays are used. This invention describes an electro-optical imaging system that achieves wide FOV global imaging for suspect object detection and local high resolution for object recognition and tracking. It mimics foveated imaging property of human eyes. There is no mechanical scanning for changing the region of interest (ROI). Two relatively small format image sensor arrays are used to respectively acquire global low resolution image and local high resolution image. The ROI is detected and located by analysis of the global image. A lens array along with an electronically addressed switch array and a magnification lens is used to pick out and magnify the local image. The global image and local image are processed by the processor, and can be fused for display. Three embodiments of the invention are descried. | 03-26-2009 |
