Create a training sample from an image collection...
IMG/pos.txt(1): Parsed errordone. Create 0 samples


Command:
opencv_createsamples.exe -vec pos.vec
  -info img/pos.txt -bg img/neg.txt -w 20 -h 20 -num100

Solution:

1: It may be in incorrect formatting:

txt file format:
1.jpg 1 0 0 20 20
2.jpg 1 0 0 20 20
3.jpg 1 0 0 20 20
4.jpg 1 0 0 20 20
5.jpg 1 0 0 20 20
6.jpg 1 0 0 20 20
7.jpg 1 0 0 20 20
8.jpg 1 0 0 20 20
9.jpg 1 0 0 20 20
10.jpg 1 0 0 20 20
11.jpg 1 0 0 20 20
12.jpg 1 0 0 20 20
13.jpg 1 0 0 20 20
14.jpg 1 0 0 20 20
15.jpg 1 0 0 20 20
16.jpg 1 0 0 20 20
17.jpg 1 0 0 20 20
18.jpg 1 0 0 20 20
19.jpg 1 0 0 20 20
20.jpg 1 0 0 20 20
21.jpg 1 0 0 20 20
22.jpg 1 0 0 20 20
23.jpg 1 0 0 20 20
24.jpg 1 0 0 20 20
2: Inconsistent numbers:

The number in the txt file is inconsistent with the number after -num

3：

When generating a VEC file, an error is reported

dressPantsPositives.txt(421) : parse errorDone. Created 583 samples
Analysis: Because when calling the default parameters, the system defaults to 1000 positive samples, if you train less than 1000 positive samples, parse errorDone will appear.

The number of positive samples can be increased to more than 1000.
