-Cross-country intelligent vehicles always work in
complicated environments with varying illuminations.
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: This a MFC program to test direct linear discriminant analysis (direct LDA) for face recognition. Histogram equalization is used as a preprocessing and direct LDA is used to reduce a dimension in feature space from train images. Minimum Euclidean distance is used for face recognition of test images. -This is a MFC program to test direct linear discriminant analysis (direct LDA) for face recognition.

Description: 1.采集到的车牌照图片使用的是24位RGB的BMP位图，即真彩图。需要将其转化为256级灰度图像。
2.将灰度图像转换成为二值图像。
3.去除噪声采用的方法：中值滤波、直方图均衡。
4.数学形态学的基本思想是用具有一定形态的结构元素去度量和提取图像中的对应形状以达到对图像分析和识别的目的。-1. Collection of vehicle license plate image using a 24-bit RGB bitmap in BMP, that is true color. Needs to be converted into 256 gray-scale image. 2. Will become a gray-scale image is converted binary image. 3. The methods used to remove noise: median filter, histogram equalization. 4. The basic idea of mathematical morphology is the structure of a certain form elements to measure and extract the corresponding image in order to achieve the shape of the image analysis and identification purposes.
