基于AVI格式的全方向M型心动图增强研究

The Research on Image Enhance of Omnidirectional M-mode Echocardiography Based on AVI Format

为了图像质量更好,基于AVI的全方向M型心动图,针对其特点进行了图像增强的研究,提出了一种特殊的利用熵选取多阈值的算法,实现了图像的多阈值分割,效果令人满意,在扩展图像的对比度、增强轮廓边缘的同时对噪声进行了有效的控制。经过实验,这种算法对心动图具有一定鲁棒性。

Based on the omni-directional M-mode echocardiography from AVI system, and according to the rebuilding principles, this paper makes some image enhance research and presents a multl-threshold entropy algorithm. The result is satisfied that the e- chocardiography is disturbed by serious noise and segmented effectively under the proper crossover rate, and carry on effective restrain to the noise while expanding the contrast ratio and strengthening the edge. It is universally applied for Omnidirectional M-mode E-chocardiography.
