In this code: Why in the for loop they use descriptors_object.rows ? Why not using the matches vector's length ? And my second question is what exactly contains a descriptors_object/descriptors_scene Mat ? Is it a 2 dimension Mat ? With the same width and height than the image used to create this descriptor ? |
