Histogram,and histogram bounding box

Question

would i go about detecting this kind of Moth based on its Histogram.i followed tutorials and i do i need to calculate it first for the isolated moth and then find that specific histogram in the webcam feed ? if so, how to search for specific Histogram values within that picture ? Also how to go about creating a bounding box around the target ?

Answer 1

What you need to do is:

1) Calculate the histogram of the "isolated moth" and store it.

2) Do backprojection with your model histogram and the input image. The zones of the image containing the histogram you are looking for should "glow" in the backprojection image.

3) If you want to generate rectangle-shaped regions with the location, use 2D moments .
