胶囊内窥镜系统图像压缩算法设计及实现
The design and realization of image compression methodology of capsule endoscope
摘要
Abstract
Objective:To design one kind of image system with high efficiency scheme of image compression, storage and transmission to meet the needs of high performance endoscope. Methods: By introducing the shielding function which owns different threshold at different decomposition scales and the optimized coding scheme based on statistical analysis. And then we validated the endoscope by professional tests.Results: Experiments and clinical applications shown this capsule endoscope realized the features of 12 fps frame rate even for 480×480 images, DOF 0~50 mm. It realized high efficiency, high fidelity compression and high speed transmission of the image.Conclusion: The energy consumption of the image storage system had been greatly reduced through the design, and the application demands of image transmission and reduction had been solved. The capsule endoscope can well meet the requirements from system monitoring and diagnosis.关键词
