Thread Subject:

How can I run a loop buy using IF statment on the picture to change the selected pixel to different color?

Develop a simple algorithm; using MATLAB or any other acceptable SW, to classify the different landscapes within the provided image:

• The algorithm requires first to read the image.
• Then gives a unique pseudo color to areas IF they fall within a similar range to one of the pointed areas in Figure1.
• Finally a one short paragraph short paragraph should be included; with the final result
• Please find the image attached…
The following are some pointers that you might find useful:
1. All colored images consist of three basic layers (colors) è Red, Green and Blue (RGB).
2. All colored images readings doesn’t go below zero (black) è Red = 0, Green=0 and Blue=0.
3. All colored images readings doesn’t go above 255 (white) è Red=255, Green=255 and blue=255.
4. Colors within an image are a combination to a certain degree between red, green and blue.
So what you have to do is make a for loop that runs through the whole image (layer by layer), then make an if condition to assign a new value to the points (pixels) that have the same RGB values as the points pointed out in the image (red arrows).

ð 1 for loop + 4 if conditions
(image + algorithm), about the different classification techniques the recruit should be able to explain one of these techniques.

This sounds like a homework question and in general this newsgroup requires
people posting homework questions (or questions that sound like they're
homework, even if they're not) to show what they've done to try to solve the
problem and to ask a SPECIFIC question before the readers will offer any
suggestions. Post the code you've written to try to solve this question and
indicate where EXACTLY you're stuck and someone may offer some assistance.
