About this app

When using Create ML to create an Object Detection model, a large amount of training data is required, and there are strict requirements for the data format, so data preparation can be time-consuming. Ex Machina makes this step quick and easy. Simply import the folder where your images are located, then draw a box around each object and give it a label. Ex Machina automatically generates and processes the corresponding JSON files for the data, ready to be imported directly into Create ML.

Baseline captured. Growth appears after the crawler observes a changed rating count.
