1.R[k]["size"]= len(masked_pixels / 4)
Why there division by 4? It's seems no influence for the len function.
2.skimage.feature.local_binary_pattern(img[:, :, colour_channel], 8, 1.0)
hist = numpy.concatenate([hist] + [numpy.histogram(fd, BINS, (0.0, 1.0))[0]])
The output range of LBP feature is (0.0, 255.0), then why the histogram range is (0.0, 1.0), that means
leave off the pixel > 1? or maybe a bug?

Hi, the 4 seems to be a magic number. And as for the second problem, it seems to be a duplicate of issue #21. I think you are correct, but as the authors have no activity for months in this repo, I do not have expectations that these bug will be fixed.

Thank you for your reply. I ever think there maybe a wrong typewrite about len(masked_pixel / 4), or the right is len(masked) / 4 for calculate the side's length of the square. But that's not reasonable, for the rectangle of region proposal is not always square~

Because the author has abandoned the repo.So I come to ask for your help.
I want to ask does the order of the final returned results follow the ascending order of the scores?
How can I see the score information in this program?
Best wishes!

And in fast rcnn,We usually use 2,000 proposals, and how do we select these 2,000 proposals? Take this program as an example.
I am a beginner in object detection.
Thank you!Best wishes!

@Mickeybaby The algorithm is based on similarity between regions, so I am not sure what you mean by “scores”. For the question about fast rcnn, I still know little about it...
