Title: Colin J Brown: Innovator in Activity Classification and Depth Estimation

Introduction

Colin J Brown is a prominent inventor based in Montréal, Canada. He has made significant contributions to the fields of activity classification and depth estimation, holding a total of 14 patents. His innovative work focuses on utilizing advanced technologies such as neural networks to enhance human activity recognition and 3D joint location estimation.

Latest Patents

One of his latest patents is titled "Method and system for activity classification." This disclosure is directed to an activity classifier system for classifying human activities using 2D skeleton data. The system includes a skeleton preprocessor that transforms the 2D skeleton data into transformed skeleton data, which comprises scaled, relative joint positions and relative joint velocities. Additionally, it features a gesture classifier that utilizes a recurrent neural network to identify the most probable gestures from the transformed skeleton data. Furthermore, an action classifier, also based on a recurrent neural network, identifies the most probable actions based on the information received from the gesture classifier.

Another notable patent is "Method and system for monocular depth estimation of persons." This patent provides systems and methods for estimating the 3D joint location of skeleton joints from an image segment of an object and 2D joint heatmaps. The process involves applying the image segment and 2D joint heatmaps to a convolutional neural network, which contains at least one 3D convolutional layer block. This method reduces the 2D resolution at each 3D convolutional layer while expanding the depth resolution to produce an estimated depth for each joint, ultimately generating an estimated 3D joint position.
