How would I go about accurately calculating the area of ice in this photo https://imgur.com/k6hx1nW
I know that its important to take a good image in the first place but I have a fair few images from past experiments that I dont want to lose.
At the moment I’m having to play around with the contrast/find edges/despeckle/make binary to make the crystals easier to identify and then using morphological segmentation to make an image suitable for thresholding (https://imgur.com/MlAIW2b) . I’ve also tried using Weka segmentation but its eating up my computer’s RAM and doesn’t seem to do a good job.
However I’m using the binary tools a lot to close open crystal boundaries which is leading to me overestimating the mass of solid in the samples.
Are there any better options to what I’m doing?
