Extracting sub-images of detected objects

Hi, firstly thanks for sharing this code. Its great.

I noticed a small snag when extracting the sub-images before feeding them into the ReID model, in this section of the code:

MOT-DeepSort-CS/src/MOT.CORE/ReID/ReidScorer.cs

Lines 124 to 127 in f59a927

 Bitmap bitmap = FragmentBitmap(image, detectedBoundingBoxes[i * _reidModel.BatchSize + j].CurrentBoundingBox, _reidModel.Width, _reidModel.Height); 

 Rectangle rectangle = new Rectangle(0, 0, bitmap.Width, bitmap.Height); 

 BitmapData bitmapData = image.LockBits(rectangle, ImageLockMode.ReadOnly, bitmap.PixelFormat); 

 int bytesPerPixel = Image.GetPixelFormatSize(bitmap.PixelFormat) / 8;

On L126, I think it should be: BitmapData bitmapData = bitmap.LockBits(rectangle, ImageLockMode.ReadOnly, bitmap.PixelFormat);

(And also, L155 would need to change too from image.UnlockBits(bitmapData); to bitmap.UnlockBits(bitmapData);)
