We can access height width and number of channels from img shape. It can be used to store real or complex valued vectors and matrices grayscale or color images voxel volumes vector fields point clouds tensors histograms though very high dimensional histograms may be better stored in a sparsemat. This article is outdated zed sdk 1 2. The idea is that you feed a mat into this function that can likely be reused since in most cases successive video frames will have the same dimensions.

In this tutorial you will learn how to use the zed sdk to capture and display color and depth images from your zed. Height is at index 0 width is at index 1. Inv int method boolean. And number of channels at index 2.
