Description: 摘要:提出了一种基于兴趣点不变矩(IPIM)的图像拼接技术。利用Harris 角检测器获取图像中的兴趣点,计算
兴趣点邻域的平移、旋转及尺度不变矩,通过比较各兴趣点邻域不变矩的欧式距离提取出初始特征点对,根据
几何变换模型剔除伪特征对,最后利用正确映射模型实现图像的拼接。实验表明,该方法对平移以及任意角度
的旋转具有良好的鲁棒性,对于具有小尺度变换的图像仍然具有很好的拼接效果。-Abstract: This paper presents a point of interest based on moment invariants (IPIM) of the image stitching technology. Angle using Harris detector to obtain images in the interest of points to calculate the interest point neighborhood of the translation, rotation and scale invariant moments, by comparing the interest point neighborhood of the Continental moment invariants extracted from the initial feature points right, according to the geometric pseudo-transformation model features removed, and finally realize the use of mapping model correctly spliced images. Experiments show that the method of translation and rotation of any angle has good robustness for small-scale transformation of the image still has a good effect splicing. Platform: |

Description: Harris detector
The code calculates the Harris Feature Points When you execute the code, the test image file opened and you have to select by the mouse the region where you want to find the Harris points, then the code will print out and display the feature points in the selected region. You can select the number of FPs by changing the variables max_N & min_N Platform: |

Description: A method to detect new objects in a scene by
comparing an input query image and a movie database captured beforehand is proposed.
Our method is based on both feature point matching and edge matching. First, we select the most matched movie from the movie
database based on the number of matched feature points. In addition,
we can get unmatched points in the query by excluding the matched points from all the extracted feature points in the query. Next, the most matched frame is selected from the most matched movie. It has the most
matched points with an input query image. Canny edge detector is applied
to both the query and the most matched frame in order to find unmatched edges. By merging the results of unmatched points and unmatched
edges, new objects will be detected. Our method can be applied to various scenes such as indoor and outdoor. In experimental results, we represent that our proposed method achieves change detection in various scenes. Platform: |

Description: 定性与定量地描述冠状动脉血管，很大程度依赖于造影图像中的血管结构识别结果，对此，提出了一种多特征模糊识别算法判别血管结构．实现过程中，首先通过图像预处理获得血管初始特征，然后利用一圆周探测器沿血管路径扫描并获取多种局部测度；在定义各种局部测度的多特征模糊子集及其隶属度函数之后，通过构造模糊识别算子准确地判别血管的端、段、分支和交叉结构．该方法在仿真血管模型和多套实际冠状动脉造影图像上获得了较好的效果，对实际图像的结构识别平均正确率达到92 。-Qualitative and quantitative description of coronary artery, a large extent depends on the contrast images of the vascular structure of the recognition result, this paper presents a fuzzy multi-feature recognition algorithms distinguish vascular structures. Implementation process, the first vessel through the initial characteristics of image preprocessing was, and then use a circular detector scanning along the vascular path and to obtain a variety of local measures in defining the characteristics of the various local measure of the multi-fuzzy sets and membership function after by constructing a fuzzy recognition accurately determine vessel operator s side, section, branch and cross-structure. The method in simulation models and multi-vessel coronary angiography image sets were real good results, the structure of the actual image recognition accuracy of 92 on average. Platform: |

Description: In the fields of computer vision and image analysis, the Harris-affine region detector belongs to the category of feature detection. Feature detection is a preprocessing step of several algorithms that rely on identifying characteristic points or interest points so to make correspondences between images, recognize textures, categorize objects or build panoramas.
