Automatic Panorama Stitching software in MATLAB. Spherical, cylindrical and planar projections stitching is supported in this version and can recognize multiple panoramas.

CrackDenseLinkNet-DeepLearning-CrackSegmentation

CrackDenseLinkNet: A deep convolutional neural network for semantic segmentation of cracks on concrete surface images (DenseNet and LinkNet combination with the compound loss)

CurvatureVisualize

Measures the shape properties of the object boundaries and displays the curvature.

Image-Cylindrical-Spherical-Projections

Transforms the color or grayscale 2D image to the cylindrical and spherical coordinates. Fast as no for-loops are used.

PCL-FeatureBased-PointCloudRegistration

A computer program on PCL framework to register two point clouds using the feature-based keypoints (SIFT, SHOT, FPFH, etc.), local/global feature descriptors, followed by various correspondence estimation and rejection methods. Below summarizes the available keypoints, descriptors, correspondence estimation and rejection methods that works in different combinations.

RGBDtoPointCloud

Creates point clouds from color and depth (RGB-D) images.

VoronoiLimitRectSquare

Provides a bounded Voronoi Diagram with vertices similar to MATLAB [vx,vy] = voronoi(x,y). In other words, prunes the edges that extend the boundaries of the given x and y values.

Weighted-Adjacency-Matrix-of-Image

Creates a weighted adjacency matrix from an energy matrix for an image. Average, similarity and dissimilarity between the nodes i,j can be computed. If a custom energy matrix is provided, the same functions can be used to fill the adjacency matrix with edge weights.
