Confused about Faster R-CNN #1

Closed Vast-Stars closed 6 years ago

Vast-Stars commented 6 years ago

I have read the code and paper. The paper mentioned that Faster R-CNN is used in detection part. But I didn't see Faster R-CNN in the folder ./detector . I search for RPN or ROI Pooling but get nothing.

Did you complete Faster-RCNN function in the data preprocessing part? Or is it just using RCNN? (If my understanding of the code is correct, the original image was partitioned and data-enhanced during preprocessing, and then used as input to the model. Looks like RCNN)

We did not use selective search for proposal candidates. Our framework is a little different from Faster R-CNN. The detection in DeepLung is one-stage. We did not use the bounding box refinement in the second stage of Faster R-CNN. This one-stage detection is a trend for both natural image object detection, and medical image object detection.

Oh, I see. Thx......(￣▽￣)"
