I've built the model with pretrained weights and a pretrained backbone directly from keras_cv. Experiment with different object detection and tracking algorithms. Here the model is tasked with localizing the objects present in an image, and at the same time, classifying them into different categories. I also use methods like resizing from Industry-strength Computer Vision workflows with Keras - keras-team/keras-cv Oct 17, 2023 · from keras_cv import bounding_box. In this tutorial, you will learn how to: Understand the core concepts and Something went wrong and this page crashed! If the issue persists, it's likely a problem on our side. Add a keras cv object detection tutorial for Keras 3 for new yolo version (yolov9 or newer) https://keras.
