Consider this as a beginner’s tutorial to Matlab image processing. Read the documentation of the commands used and try and understand what they are doing and why. 1. Read the image Use imread to read the image into a 3D matrix. For convenience, we convert it to double in the range [0..1] using im2double: >> … Read more
I guess an first order interpolation is what you want. How to handle the funktion interp1 is explained in the Matlab Manual. 1 solved How I can insert data to table in MATLAB? [closed]
As schorsch said in comments, simply do: A=M(160:430,108:305) to get values then modify your sample ( B=transform(A) ) and put B in the same way you got A out M(160:430,108:305)=B Remember that : basically means everything in between I agree with Mark though, the documentation for MATLAB is outstanding and one of MATLAB’s best features … Read more
The simplest way is just to call it in a loop: x = zeros(1,100); for i = 1:100 x(i) = my_func(); end And then: hist(x) solved How to generate samples from a random number generator in matlab? [closed]
You can use java libraries for linear algebra and matrices algebra for that. Or if you are trying to write greyscale a bitmap search for a java library that does that. Android most outer layer runs on Java language mostly 2 solved I want to write this cod e in android it is in MATLAB,
rank in matlab 2014a uses svd, not svds. If your local file uses svds the installation is corrupted. I recommend to reinstall Matlab and set write restrictions to the toolbox folder afterwards to prevent such problems happen again. solved Matlab rank function bug [closed]
Nonlinear arbitrary-directional broadband piezoelectric vibration energy harvester using 3-DOF parallel mechanism by matlab [closed] solved Nonlinear arbitrary-directional broadband piezoelectric vibration energy harvester using 3-DOF parallel mechanism by matlab [closed]
You can group the results of regionprops into a vector and use it for indexing: rg = regionprops( L, ‘Area’ ); allArea = [rg(:).Area]; % grouping all area values into a single vecotr labels = find( allArea >= 300 & allArea < 500); % select relevant regions solved Returning specific regions [closed]
Generally I’m not in the habit of answering questions that clearly prove you haven’t tried anything yourself. Today is no different, but I’ll do the following: I’m gonna provide you with a little code, that contains a few intentional errors. It’s up to you to figure out what the code does, and where the problems … Read more
The only problem with MATLAB, for a beginner, is that it is really expensive. Some universities buy it without the Image Processing Toolbox, in which case it is not so useful. Octave is well supported by the open source community, that is another alternative “Processing” is a language that is easy to learn and powerful. … Read more
