(Image processing) new image with the specified color

Hello everyone,

I would like to ask for the code or method that would help me get a new image containing only the color that I want.

For example: I have an image that contains only 2 red lines, what code or method would help me get a new image that only contains the color red in the original image(in my case the 2 red lines).

And thank you,

Daniel.

To separate out the red lines you may convert the RGB image to HSV (Hue-Saturation-Value) image. HSV separates the image intensity from the color information. Then you can use the color information of the HSV image to filter out a specific range of colors. For more you can refer the following answer

Try using the Color Thresholder app on the Apps tab of the MATLAB tool ribbon. Use the export button to create code (a function) from what you did interactively.
