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
