I am analyzing some particles to quantify the amount of surface area that have specular highlights or are “glossy”. Here is an example:
Breaking the problem down I need to:
- select the particle from the background and calculate the total area
- select the glossy parts on the particle only and calculate the area
By adjusting the threshold, I can select most of the particle–only some of the glossy parts are not selected and if I adjust the threshold enough to select the glossy parts, then the background is also selected. At the same time, if I adjust the threshold in order to select the glossy parts of the particle the background is selected.
I’ve tried a few different things with the end result that I have been unable to separate the background, particle, and glossy parts on particle. This is my first time doing image analysis and I’ve been struggling with this for a week. I’m not even sure I’m using the correct terminology.
