Vision Classification

+

Train your computer to recognize images

+
+

Create a New Classifier

+

Train a new image classifier with your own examples

+
+ +
+

Getting Started

+

To train a vision classifier:

+
    +
  1. Create a new classifier and give it a name
    2. +
  2. Add at least 2 labels (categories) for your classifier
    3. +
  3. Upload at least 10 example images for each label
    4. +
  4. Train your classifier
    5. +
  5. Test your classifier with new images
    6. +
+

+ + Read the full guide + +
