Very new to this. I just downloaded Fiji and am attempting to use the trainable segmentation weka to help separate between giant vesicles and background solution. However, it keeps freezing or is unable to completely analyze the image (with no error message). It gets caught on “updating features of slice 1”. How long does it typically take to apply the first set of applied classifiers/ first training? I’m wondering if it’s something to do with my image (pasted below). I want it to recognize the difference between the vesicles (specks) and background, although this image was taken on a hemocytometer so I’m not sure if the gridlines are making it difficult to analyze.
