CS231n

Visual recognition problem

- Image classification

- 3D modeling

- Grouping

- Segmentation

CS231n focuses on one of the most important problems of

visual recognition, especially image classification

4 / 26

Image classification focus on the whole big image

There is a number of visual recognition problems that are related to image

classification, such as object detection, image captioning
