The paper presents a new cross-country obstacle
detection technology based on stereo vision system.
The original images are preprocessed by Gaussian
filter and contrast-limited adaptive histogram
equalization (CLAHE) method to weaken the effect of
noise, light and contrast. Harris corners are located
with sub-pixel accurate. To guarantee the overall
system real-time performance, feature-based matching
techniques are studied and fundamental matrix is
calculated based on random sample consensus
(RANSAC). Also restrains are studied to eliminate
pseudo matching pairs. Then data interpolation is
introduced to build elevation maps. Edge extraction
and morphological processing are concerned to
accomplish obstacle detection. Experiment results for
different conditions are presented in support of the
obstacle detection technology. Platform: |

Description: 采用对比度受限自适应直方图均衡对乳腺图像进行增强，有效地增强了乳腺图像中的细节，如钙化点、乳导管等组织；并通过对算法中相关参数研究， 得到应用于乳腺图像增强的参数优选值，以求获得较好的增强效果，为医师分析影像提供方便。通过与灰度直方图均衡的结果进行比较得出：对比度受限自适应直方图均衡为乳腺数字图像增强的有效方法， 在计算机辅助乳腺诊断方面有较高应用价值。-By contrast limited adaptive histogram equalization image of breast enhancement, effectively enhancing the breast image details, such as calcification, milk ducts and other organizations and through the relevant parameters of the algorithm, are applied to image enhancement breast parameter optimization value, in order to obtain better enhancement for physicians to facilitate image analysis. Balanced with the histogram obtained results were compared: the contrast limited adaptive histogram equalization for the breast and effective methods of digital image enhancement, in computer-aided diagnosis of breast have a higher value.
