This function can be used instead of CONV2 (with the same arguments). It will produce the same results to within a small tolerance, and may be faster in some cases (and slower in others). Two additional shape options are included, offering periodic and reflective boundary conditions.

to understand the Algorithm go to matlab help in page dct2 and idct2 to get the mathematical expression for M = N = 8, we can calculate the most of hard values and save it as LUTs to speed up the execution now compare our special 8X8 functions with the internal general functions use this code: A = int32(100*rand(8,8)); tic;for i = 1 : 1000 IDCT_8X8(DCT_8X8(A));end;toc; tic;for i = 1 : 1000 idct2(dct2(A));end;toc; i had built the general functions too, but with low speed.

The attached Matlab routines compute the medial axis of 2-D solids whose boundary is made-up of line segments and circular arcs. Caveats: * The attached code is slow. * There are also a few bugs that we are aware of, and expect to address them; use the code with caution! * You will need the Matlab optimization toolbox.

Since I have to do a lot of plots after doing PCA on my data I?ve written this small ?programs? using GUIDE . =>Fastplot button uses plot command and can be used in combination with removepoint (code of this function is a small modification of removepoint made by Jean-Luc Dellis) for doing ?automatic plots? (no need of custom input for choosing every class symbol and color).

This is a very fast and efficient script for nodal-to/from-spectral transforms using chebyshev polynomials on the unit square domain. This version does not require 2^n truncation, but does require the same truncation in both dimension. Users are encouraged to improve and redistribute this script.

  • Platform: Matlab, Scripts

This MEX performs 2d bilinear interpolation using an NVIDIA graphics chipset. To compile and run this software, one needs the NVIDIA CUDA Toolkit (http://www.nvidia.com/object/cuda_get.html) and, of course, an NVIDIA graphics card of reasonably modern vintage.

Recent studies on Mathematical modeling of visual cortical cells [Kulikowski/Marcelja/Bishop:1982] suggest a tuned band pass filter bank structure. These filters are found to have Gaussian transfer functions in the frequency domain. Thus, taking the Inverse Fourier Transform of this transfer function we get a filter characteristics closely resembling to the Gabor filters.

function H = hist2d(D,Xn,Yn,[Xlo Xhi],[Ylo Yhi]) Calculates and draws the 3D histogram of 2 Dimensional input data D. Counts number of points in the bins defined by X = linspace(Xlo,Xhi,Xn) and Y = linspace(Ylo,Yhi,Yn) D must be a 2 column or 2 row matrix or an array of complex numbers [Xlo Xhi],[Ylo Yhi] are optional and default to the min and max of the input data Xn and Yn are optional and default to 20 Example: hist2d([randn(1,10000); randn(1,10000)]) Really just a copy of 2D Histogram, by Rey Patlolla, but with default arguments, optionally complex input and draws a 3D histogram.

Calculate the 2D histogram of data pairs [x,y] on a 2D grid defined by its edges. Allows 'fast' and 'exact' binning modes. Adjustable input grid mode. Output of mesh centers for easy plot. EXAMPLE: binEdges_minmaxN_xy = [10 100 91; 0 10 21]; [h2d, binC_x, binC_y] = hist2(data2d, binEdges_minmaxN_xy, 'fast'); imagesc(binC_x, binC_y, h2d); % a 90x20 grid In "exact" mode it will equally split each point that falls on the bin edge between the two (or four) adjacent bins.

function histmat = hist2(x, y, xedges, yedges) Extract 2D histogram data containing the number of events of [x , y] pairs that fall in each bin of the grid defined by xedges and yedges. The edges are vectors with monotonically non-decreasing values.

ZI = mirt2D_mexinterp(Z,XI,YI) interpolates 2D image Z at the points with coordinates XI,YI. Z is assumed to be defined at regular spaced points 1:N, 1:M, where [M,N]=size(Z). If XI,YI values are outside the image boundaries, put NaNs in ZI. The function is similar to Matlab's native ZI = INTERP2(Z,XI,YI,'linear',NaN), but is much master.

http://simulations.narod.ru/ There was try to simulate 2d liquid in rectangle vessel without air in matlab. The idea was to use voronoi graph to separate liquid into pieces. Each piece has forces: 1) friction from neighbor, proportional to contact edge length 2) friction from wall if any 3) pressures from neighbor Each piece has pressure that defined from area of polygon and compare it with initial area.

The algorithm computes the minimal distace between two segments. It also manage the case of parallel segments and null length segments. The algorith is inspired by Franz J. Vesely at http://homepage.univie.ac.at/Franz.Vesely/...ks/hst/hst.html.

this function plots the 2D multivariate gaussian when the mean and covariance are provided. It does not use for loops. ex: plot mean=[10;11],cov=[6 0;0 6] 2D multivariate gaussian function >> mvg([10;11],[6 0;0 6]).

Use coeffs = fit2dPolySVD(x, y, z, order) to fit a polynomial of x and y so that it provides a best fit to the data z. Uses SVD which is robust even if the data is degenerate. Will always produce a least-squares best fit to the data even if the data is overspecified or underspecified.

The first just does detection by background subtraction. This can be considered as the ground truth. The second feeds the detection output into a Kalman filter. The predicted position from the kalman filter (red) is compared against the actual ground truth position (green).

The files in this package comprise two Matlab functions that create visualizations of 2D vector fields. cquiver renders a vector field as a grid of unit-length arrows. The arrow direction indicates vector field direction, and the color indicates the magnitude.

polyfitweighted2.m and polyval2.m --------- polyfitweighted2.m: Find a least-squares fit of 2D data z(x,y) with an n th order polynomial, weighted by w(x,y). polyval2.m: Evaluate 2D polynomial produced by polyfitweighted2.m. Usage polyfitweighted2 ----- P = polyfitweighted2(X,Y,Z,N,W) finds the coefficients of a polynomial P(X,Y) of degree N that fits the data Z best in a least-squares sense.

Features of the toolbox: (1) The toolbox includes classic level-set methods such as geodesic active contours (GAC), Chan-Vese model and a hybrid model combining the boundary and regional terms. (2) All the methods are implemented with the semi-implicit solver AOS which can guarantee the stability of the numerical methods even with very large time steps, thus boosting the efficiency for level-set based segmentation.

These are the codes in "A note on two-dimensional linear discrimant analysis", Pattern Recognition Letter' In this paper, we show that the discriminant power of two-dimensional discriminant analysis is not stronger than that of LDA under the assumption that the same dimensionality is considered.

This is a tiny project just to show how we can build a useful tools from the available graphics commands in MATLAB . In this project I had been used the "Plot Annotation" Commands to write a program in Simulink using "Embedded MATLAB Function" block to plot the vectors in 3-phase systems.

This program will generate the coordinates of a 3D Bresenham's raster line between two given points. A very useful application of this algorithm can be found in the implementation of Fischer's Bresenham interpolation method in my another program that can rotate three dimensional image volume with an affine matrix: http://www.
