@It'sPronouncedOiler Alright, so there is hope that my effort won't be wasted :) Re-thx.

comment Tracking features where ImageFeatureTrack finds none?
@It'sPronouncedOiler Thx, I'll try that (too). In your experience, does the input look reasonable for feature tracking in general? Maybe the "animation" is too course, i.e. deltas between occurrences of same features are too big?

comment Image processing for extracting regions of book pages that are covered by text
@rasher Bluring, binarizing (as mentioned), and various filters mentioned under segmentation analysis. Unfortunately, the results are no good (not worth posting).

Tx, now it's perfect.

If you try this with HighlightImage as f it will complain about expecting an image instead of a list of images.

comment MapThread (or alternative) for adding fixed option
This is close, but this Inner sums elements, wheras I need a list of elements. f is e.g. HighlightImage.

comment Ways to overcome failure of TextRecognize on relatively simple price tag?
@Murta The answer to both questions is yes. (Extracting the promoted price, e.g. 13.80 €, is most important.) Perhaps it is possible to first split the image into boxes with similar-sized letters and do separate OCR on each.

comment Ways to overcome failure of TextRecognize on relatively simple price tag?
@P.Fonseca Thx for your reply. If I can help it, I would prefer not to introduce assumptions about the inner geometry of the box. I've meanwhile noticed that e.g. prior black-and-white conversion with ColorSeparate[image, "HSB"][[2]] helps (a bit), so I'm still optimistic.
