Hough transform for circles in any size. returns a list of all circles found (position and radius) in an RGB image.
includes function for: drawing a circle on an image. finding the maximum points in a 1d signal.
The intention is to make a more flexible and more general function than the Matlab function dblquad. Especially the domain may be given in a more general way, it may be a circle, a rectangle, or any convex polygon. Also different methods may be...
DRAWEARTHSHADED Draws a shaded map of the Earth
DRAWEARTHSHADED Draw a map of the earth, with a realistic set of colors. This can be used as a background for any map plot you wish. It is important to note that the...
This function takes points drawn on x-y axis and maps them to a sphere in real time. Click and drag on the planar area to draw a series of dots (one graphic object).
Function HISTF ('flexible histogram') extends Matlab's HIST by letting one bound displayed percentiles, set x-axis limits and y-axis maximum, set x bin size, and draw a marker line at given x position. In contrast to HIST, relative rather than...
DS AnalogClock can be incorporated into your web page to display an analog clock. The numbers from 1 to 12 is displays in a circle and supports three needles to denote the hour, minute and seconds. The position of the clock, clock size, color of...
A simple gui design shows the ability to make dynamic plotting by changing the value of slider which produce a change in the circle radius.
Maximum Inscribed Circle Or in other words, "largest inner circle" , "maximum empty circle" etc.
This is a very common problem in computational geometry, and it is not simple to solve efficiently.
Usage: [mfTutteMap] = TutteMap(mnTriangulation)
Maintaining the existing triangulation, this function maps a surface mesh onto a planar unit circle. Tutte's algorithm [1] is used. The simple technique for finding point locations is from...
A collection of M-Files capable of drawing a standard colored smith chart including all the labels and scales which can be found on a standard smith chart. In addition it allows other lines and circles to be drawn on the standard chart.
H = DRAWRECTANGLE(PARAM,STYLE) This function draws a rectangle with the given parameters: - inputs: param................... 1x5 array - param = [a, b, w, h, theta] - (a,b): the center of the rectangle - (w,h):...
ADDBORDER draws a border around an image.
NEWIMG = ADDBORDER(IMG, T, C, S) adds a border to the image IMG with thickness T, in pixels. C specifies the color, and should match the color format of the image (e.g., RGB or indexed). STROKE...
A common request is to interpolate a set of points at fixed distances along some curve in space (2 or more dimensions.) The user typically has a set of points along a curve, some of which are closely spaced, others not so close, and they wish to...
This completely vectorized code helps you find all points within a cut-off radius from given point. Say, in applications such as Molecular Dynamics, you may be required to find out which atoms lye within a cut-off radius (for example, the...
This demo requires you to be using a Linux machine and to have libfreenect installed with the python wrapper. This demo also requires you to have opencv, numpy, and pygame. They can all be installed using sudo apt-get install {PROGRAM NAME HERE}....
Intended for 3D geological/geophysical visualisation of layered data and will eventually form part of a geophysical visualisation package. Run ThreedDemo to get an idea of how to use.
INPUTS: LayerN: The number of the layer to be...
The purpose of the development of this toolbox was to compile a continuously extensible, standard tool, which is useful for any MATLAB user for one's aim. In Chapter 1 of the downloadable related documentation one can find a theoretical...
First keep in mind that this is not a MATLAB tutorial. This is just a list of tricks I have found useful while writing my toolboxes available on the MATLAB Central repository.
You can e-mail me if you have corrections about these pieces...
For the description, I took the abstract of the original publication: "A special set of computer-generated complex tones is shown to lead to a complete breakdown of transitivity in judgments of relative pitch. Indeed, the tones can be...
A Reuleaux triangle is a shape of constant width based on an equilateral triangle. Its not actually a triangle, but it has some interesting properties. Formost, constant width means that in principle it would make just as good a cross-section for... |
