This implementation includes modules for radiometric enhancement of colored 3D point clouds. The introduced method balances the colors of -preferably but not necessarily- overlapping point clouds in such a way that the color variances in overlapping parts of the point clouds are reduced. See other postings of the author for very fast loading and saving of n-dimensional, possibly colored and bulky point clouds. The implementation is based on...
This implementation includes modules for radiometric enhancement of colored 3D point clouds and nearest neighbor search. The introduced method detects the overlapping parts and derives a transformation function that reduces radiometric...
From 3D point clouds , we can computed for each point how they deviate from tangent plane. This algorithm very useful for point simplification .
This implementation includes modules for very fast loading and saving of n-dimensional, possibly colored and bulky point clouds. The proposed functions can also be used to load and save matrices in ASCII format.
USAGE -------
This is a simple utility for estimating the rigid transformation that aligns two sets of 3D point clouds, given 3 (or more) point matches.
Input: two sets of 3D point clouds (P1 and P2) Output: homogeneous transformation that...
OpenCOCONE is a software library for creating triangulated surface models from point clouds with an algorithm called as COCONE. The COCONE algorithm itself is created by Tamal K. Dey.
Uses a loop in order to plot colour classes as line objects (plot3) for colouring 3d points.Much faster than scatter3, does not need as much memory.Very useful with large point clouds.
Lets the user select a point from a 3D point cloud by clicking on it. The selected point is highlighted and its index is printed.
This is a useful tool if you work with 3D point clouds. You can change the mouse click callback function...
Tag clouds are web navigational elements that consist of key expressions used to identify content on a website.
They often look messy and out of place on many web pages.
This script will help programmers and/or visitors to...

An essential step in embedded software development, floating- to fixed-point conversion can be tedious, labor-intensive, and error-prone. System engineers frequently design algorithms in floating-point math, usually double-precision. This format...
ICP - Iterative Closest Point algorithm, c++ implementation. Handles only points in R^3. Makes use of a kd-tree for closest-point search. ICP finds the transformation of points in data to fit points in model. Fit with respect to minimize a...

Plot step response of PT2 (two PT1s) Calculate tU, tG, damping and inflection point.
Calculates point biserial correlation and tests for significance with either ttest or ranksum test.
Calculate the distance from a point to 2-D polygon, and the point on the polygon closest to the point.
This is based on the function made by Michael Yoshpe. Also include the test suggested by Eric Schmitz.
