2018-01-16 04:27:54 -0600 marked best answer opencv YOLOv2 vs darknet YOLOv2; is the results should be similar or different?

This is the result of OpenCV YOLOv2 image description

While this is the result of using darknet YOLOv2 image description

May I know why opencv YOLOv2 is different from darknet's? Should both of the results are different? If I'm wrong in any way please do correct me.

cfg = "yolo.cfg" weights = "yolo.weights" names = "coco.names" threshold = 0.24

Hello, I'm totally new on opencv3.2, I'm trying to create a project that uses SIFT and SURF function for acuracy comparison. The problem I've encountered is : After the building process ended for Build x64 of ALL_BUILD (combining existing opencv3.2 resources with xfeature2d modules from Open_Contrib from github) using Microsoft Visual Studio 2017, these are the error listed in the form of:
