10 min readTo implement a sliding window in TensorFlow, you can make use of the built-in crop_and_resize function or create a custom function using Tensor operations. Here's a brief explanation:Using the crop_and_resize function: TensorFlow provides a pre-built function called crop_and_resize, which is commonly used for implementing a sliding window. Given an input image and a set of bounding boxes, this function crops and resizes each bounding box to a fixed output size.
