Scilab is very powerful for digital image processing. The toolboxes SIP and SIVP add this power to SCILAB.But sadly this aspect of scilab is not used in many places. Many buy propitiatory software or use pirated copies. Also it is needed to add more routines for image processing in SCILAB. With these aims A blog has been started. http://www.scilabimge.blogspot.com Please feel free to comment and post your ideas in this blog. Kannan Balakrishnan
We sometimes use a system on which the graphics drivers cannot be used by Scilab. This happens for example on some Linux Ubuntu systems, especially on laptops.
In order to avoid this, we can configure the .scilab startup file and turn off the canvas by typing: usecanvas(%f)
The problem is that turning the canvas off with the usecanvas function also displays the message.
In order to workaround this problem we may use the following trick:
This will give an overview of optimization features available in scilab.I focus on user's point of view that is we have to minimize and maximize an objective function and must find a solver suitable for the problem.This gives an overview of what problems can be solved by scilab and what behaviour can be expected for those solvers.I will be trying to minimize/maximize a given cost function f(x) with or without constraints.Scilab is able to deal with 4 types of problems:
i)Linear problems with linear constraints
ii)Quadratic problems with linear constraints
I want to ask officials from IITB and Scilab Const. that is Scilab available for Aakash (Android)? As this information was previously looked in Wikipedia on Aakash topic. But this information is now removed from Wikipedia, that's why I am bit confused about availablity of Scilab for Android.
Can anyone clarify this doubt?
Hey i am working on SIVP and ANN toolbox of scilab. I have already tried out these in Matlab and Octave.
If anyone is working on it or wishes to do so, we can start discussing here, as it can help the new scilabians..
I was introduced to SciLab by prof. Kannan of IITB while we were both participating in an International Conference on Green Technologies at PMU, Thanjavur, TN. I have been greatly fascinated by it. It seem s to be a true replacement of the overpriced MATLAB and even more. I have downloaded the Free e-book, SciLab - A Hands on Introduction by Satish Annigeni. I paln to teach the Mathematical Modeling and Computer Simulation Course to our M.Sc.Tech. students through SciLab this semester. Humble beginning but a road to renaissance in the academics.
It's truely nice to write the codes for the problems which are worked in text books, learning the software. Scilab provides a basic platfofm for being interpreners, a great opertunity to get to know our potential.
thankx for the open source intership and helping me to learn new ans useful language like sci-lab
Image types determine the way the computer interprets data matrix elements as pixel intensity values. SciLab has the special capability of converting between image types for necessary purposes.
Images can be imported to SciLab and converted to different representations simply using SIVP module
//Making use of SIVP - Scilab Image and Video Processing Toolbox
I = imread('lena.png');
J = rgb2gray(I);
K = im2bw(I, 0.3); // 0.3 being the threshold
