2017-01-26 07:35:04 -0600	commented question	extract rgb channel images in Android Java? Sir can you provide the alternative for that? At least a guide will be very helpful, thank you.
2017-01-26 05:52:37 -0600	asked a question	extract rgb channel images in Android Java? `int mypixelColor; for (int i = 0; i < pic.getHeight(); i++) { for (int j = 0; j < pic.getWidth(); j++) { mypixelColor= pic.getPixel(i,j); byte blue = (byte) ((mypixelColor & 0xff)); byte green = (byte) (((mypixelColor >> 8) & 0xff)); byte red = (byte) (((mypixelColor >> 16) & 0xff)); bluepic.setPixel(i,j,Color.rgb(0,0,(int) blue+255)); greenpic.setPixel(i,j,Color.rgb(0,(int) green+255,0)); redpic.setPixel(i,j,Color.rgb((int) red+255,0,0)); } }` My purpose is extract bluepic channel,greenpic channel and redpic channel. there is a an error which i am unable to resolve/figure out. I think it is about loop termination. Anybody can help will be appreciated.
2017-01-24 08:46:22 -0600	commented answer	how do I separate the channels of an RGB image and save each one, using the 2.4.9 version of OpenCV? The code really helped me. I just want to ask about end results of channels, they are really red, green and blue channels images like in matlab or in grayscale(three same images but different ray level)? I am asking this because I get the color of channels iin grayscale instead of red, green and blue channel image respectively, thanks in advance.

2017-01-21 11:27:51 -0600	commented answer	How to read the pixels of the three channels at the same time? Hello Sir, I tried your code in my Android application in Java using openCv library, it did not work, I just wanted to split the colorful bitmap image into its three different rgb channel images. It will be so great if you could help me in this situation.
