(The mask RCNN practical course of computer vision object detection general solution framework aims to help students quickly master the current mainstream solutions in the field of object detection and the construction principle of network framework, and interpret its application fields and application methods based on open source projects Through the debugging method, interpret the core source code of each module in the project in detail, and understand the network implementation method and modeling process from the perspective of code. In order to facilitate the students to apply the project to their own data and tasks, an example demonstrates how to make labels and code adjustment methods for their own data sets, as well as the whole process of practical operation, and explains the complex network architecture in a simple way.)
