Introduction to Object Detection for Self Driving Cars

So, far we've been manipulating and transforming color values. But they only capture one aspect of an object's appearance. When we have a class of objects that can vary in color, structural ques like gradients or edges might give us a more robust presentation. Let's look at this realistic image, for example, this 64 by 64 pixel image of a car. And let's compute the gradient magnitudes and directions at each pixel.
