My Haarcascade classifier uses a vector file of -w=20, -h=20 for training. There are some false negative results when testing. Does increasing -w and -h improve performance of my Haarcascade classifier?

How do I evaluate the performance of Haar Cascade in test data ? How do we classify the set of images in different categories using Haar Cascade, just like CNN does?
