Hello, I am doing this image processing programming for pseudocoloring. aFile = File.new("mix.lut","w+") for i in 0...256 red = i*i/255 green = Math.sqrt(i). to_i blue = i aFile.puts "#{red} #{green} #{blue}" end aFile.close I made this simple color LUT, and i want to apply it to an image (RGB image). I could not figure it out what method to apply it.

I want to create an android app where a live camera stream captures obstacles on the ground and issues warnings to the user. This is intended as an application for the visually impaired. I'm at a loss to understand what technologies are most suitable for this as I have no previous experience in image processing. I looked through some OpenCV examples, but they didn't provide me with much insight as to where to start the project from. What I need to know is; 1. Any tutorials that might help me to get started on the project (should I start with …

What are the latest trends in steganography (hiding message in another medium e.g. digital images, videos, sound file) and steganalysis(detecting presence of message in a file) in jpeg images? Is there a way to perform steganography or is there an existing steganography algorithm where the message will not be destroyed even if filters(e.g. binarize,blur,grayscale,etc) or modifications are applied on the stego-image? Thank you and Happy New Year!

Hi, I am trying to make an image viewer, this is my first time developing a software and I was just wondering how to add properties in my application. I'm creating this software with the help of Gtk and C and now I'm stuck because I want to display the properties of an image(the default properties displayed by windows) when the user clicks on "Properties", but I don't know what function of windows.h can achieve this. Please help by giving a useful link or a small demonstration. Thanks a lot.

Is there a reliable method to extract the quantized DCT coefficients of a jpeg image? I can see that there is the jpeglib for manipulation of jpegs but I am wondering if someone has already used it and does the job I want to do. To extract the quantized DCT coefficients of each 8x8 block of a jpeg image. (As a matter of fact we are talking - I think - about decompression of a jpeg.) Any other solutions that may apply are fine too. Thanks. PS: I am trying to do a steganography project here...

Hi, I wrote a program for detecting circles using Hough Transform using OpenCV in C. The program inputs 3 images, each image contains a fixed small circle and a big circle with variable position. The program then recognizes both the circles and marks the centres of both the circles. Now what I want to do is that in the output image the (x,y) coordinates of the centre of the bigger circle should be displayed with respect to the centre of the fixed smaller circle . Here's the code for 'circle.cpp' [CODE]#include <cv.h> #include <highgui.h> #include <math.h> int main(int argc, char** …

Hi, I am a rookie coder. My goal is to incorporate the magick++ features of reading and converting different image files to an existent project. So how do I go about this? Should I download the binary installer or the source files? And what to do after that? I am using Windows 7 Home Basic (64bit OS) and Visual C++ 2010. Could you please tell me how to go about this? I really appreciate this. Thanks, Tamoghna Roy.

hi. im doing an edge detection which will detect edges of each RGB channel and then combine them to show it as a final output. im now having a problem with combining the three as it doesnt show me a binary image, instead it has some colors on it. i have checked each binary image of the RGB and it works fine which gives the black and white image. to be clearer, following is the code: [CODE]private void processActionPerformed(java.awt.event.ActionEvent evt) { width = inputimage.getWidth(null); height = inputimage.getHeight(null); inputbuff = new BufferedImage(width,height,BufferedImage.TYPE_INT_RGB); Graphics r = inputbuff.getGraphics(); r.drawImage(inputimage, 0, 0, null); r.dispose(); …
