Object classification using deep learning
Object recognition is a process of identifying a specific object in an image or video sequence. This task is still a challenge for computer vision systems. Many different approaches of object recognition including the traditional classifier or deep neural network were proposed. The objective of this...

Object recognition is a process of identifying a specific object in an image or video sequence. This task is still a challenge for computer vision systems.
