I want to try openCV, but I get completely stuck with no real error message at all. I tried a lot of different approaches, but even the simplest doesn't work whatsoever.

Workflow for the simplest:

Use the openCV comandline to mark positive samples and generate an annotation file. To make it as simple as possible, I tried 1 positive sample, resulting in this annotations file:

F:\\temp\\opencv\\positives\\0.png 1 45 35 38 63

Next I made a folder containing negatives with 20 negatives (tried .png and.tif)

Next up is the samplepreparer:

negatives: use existing (tred overwrite too)

positives:

number of samples: 1

width/hight 200 and 200 (tried numorous different values)

I allocate a negatives and vec file location and that's it. No spaces in anny of the folder structures.

I get rejected features.

Storing feature(s) to FME feature store file `F:\\fmetemp\\wb-cache--PkosFd\\Main_RasterObjectDetectorSamplePrepar -1 19 fo 1 _lt_REJECTED_gt_ 0 9db0cf751f86d66944dfbb4c75f54d358bd7f17d.ffsupdating'

Creator_CREATED_-1_20_Player (RecorderFactory): Played back 1 feature(s) from file `F:\\fmetemp\\wb-cache--PkosFd\\Main_Creator -1 15 fo 0 CREATED 0 11b5656fcc71b159fce42912dc7f3f1439c50cdd.ffs'

I tried the samplegenerator in an even simpler way:

1 negative image (.jpg)

of course 1 postive (.jpg)

DIfferent width and height settings. different numbers of output. Tried it all and it all results in rejected without an error message,
