Approximation theory

Haar space

In approximation theory, a Haar space or Chebyshev space is a finite-dimensional subspace of , where is a compact space and either the real numbers or the complex numbers, such that for any given there is exactly one element of that approximates "best", i.e. with minimum distance to in supremum norm.

Haar Cascade Object Detection Face & Eye - OpenCV with Python for Image and Video Analysis 16

In this OpenCV with Python tutorial, we're going to discuss object detection with Haar Cascades. We'll do face and eye detection to start. In order to do object recognition/detection with cascade files, you first need cascade files. For the extremely popular tasks, these already exist. Det
