Implementing Image Semantic Segmentation and Object Detection with Python

Image semantic segmentation and object detection are two key tasks in computer vision. Semantic segmentation classifies each pixel in an image into a specific category, while object detection identifies objects and determines their locations. This guide demonstrates how to implement both tasks using...

Saving and Restoring TensorFlow Models: Checkpoints, MetaGraphs, and SavedModel

Saving and restoring in TensorFlow depends on the API level you use. In graph-mode TensorFlow 1.x, checkpoints capture Variable values; graph structure can be reloaded from a MetaGraph. In TensorFlow 2.x/Keras, the recommended format is SavedModel (or H5 for Keras-only models), and object-based chec...
