This function OPENSURF, is an implementation of SURF (Speeded Up Robust Features). SURF will detect landmark points in an image, and describe the points by a vector which is robust against (a little bit) rotation ,scaling and noise. It can be used in the same way as SIFT (Scale-invariant feature transform) which is patented. Thus to align (register) two or more images based on corresponding points (see example3.m), or make 3D...
This function is a more robust and improved version of my previous submission, matchingpursuit.m
This function computes the projection of a given input vector or matrix onto a "dictionary" of other vectors or matrices using a...
clickfit_OH.m lets you mouse-click a series of datapoints on top of a (noisy) scatterplot and returns a spline or polynomial regression through the clicked dataseries. In addition the clicked series itself is returned.
clickfit_OH.m uses an...
This function convolves two very large vectors very quickly. Enormous gains in speed are due to the use of two fft's and an ifft. To find out how to use this program, put it in you 'work' folder and type "help fconv".
HICUT.m takes an input signal (vector) and removes all frequencies that exceed a chosen value.
To find out how the function is implemented, place HICUT.m in your Matlab work folder and type "help hicut."
LEGENDBAR places your items in legend in just same way as they stacked in bar, from the first item at lowest place up to last item at highest place.
Don't forget to write the corresponding strings in opposite order as well!
I was not able to get the peaks from my experimentally obtained data because of its random nature. As a result the findpeaks() defined in Matlab library was not giving results as expected. Hence I made a code which will help findpeaks() help...
% H = SIGMAPPER(CONSTELLATION, MAPPING) constructs a SIGMAPPER object H to
% map a bitstream to the points of a signal constellation. The signal
% constellation is specified by the vector CONSTELLATION which...
This function can be used to
1) Personalise your photographs
2) Add signatures to your photographs
The input to this function are two pictures -
Input 1: your photograph
Input 2: your signature
Note : 1)...
his function takes a picture in one format (e.g. jpg) and saves it in another format (e.g. eps). Availeble formats are the ones that MATLAB supports, see "help print", "help fileformats".
This program has a simple menu. The "Help - About . . . " dialog is simulated using the cMsgBox class.
It performs no other function. g the cMsgt;
This is an old program (1.999) that I have written for understanding radiation patterns of antennas. Basically I was looking for the relationship between interference diagram (Fourier transform of ilumination, usually called Array Factor) and 3D...
This functions displays GUI for selecting square or rectangular part
of the input image IMG. To perform selection user must click mouse twice:
at two corners of the selection area.
User can change the shape at any moment, even...
This function deconvolves one extremely large vector out of another extremely large vector very quickly. Enormous gains in speed are due to the use of two fft's and an ifft. To find out how to use this program, put it in you 'work' folder and type...
Description with "help R64einlesen02"
Sorry the description is in German
This function generates a Walsh-Matrix which can be used to perform the 1D-Walsh transform on a vector:
>> walsh(4)*[1 2 3 4]'
The returned matrix is internally cached within the function (persistent) which...
This function takes an audio vector and a constant as inputs. The output is the input audio vector but with a distortion effect added to it. The effect is much like that of an overdriven guitar amplifier. GDIST.m also works well with many other...
Provides linear and quadratic interpolation methods for functions defined on scattered 2D datasets.
The quadratic method in tinterp seems to be superior when compared to the cubic method in gridata.
Just catch the Forbidden Donut (nothing to gain...).
Quote of an anonymous player:
"I'll catch it ......wooh Marge, I'm in the FEX !!!"
Type "help fdonut" for more details.
This is pretty much the standard, jet plane like, flange effect. The input variables may require a little experimentation to get a good hold on.
For instructions and an example on how to use this function, put FLANGE.m in your MATLAB...
