This study proposed a breathing rate monitoring strategy using a mono camera to track and detect sleep apnea phenomena. Breathing rates were first tracked among consecutive image frames. The human body area was then isolated and magnified using a deep neural network (DNN) model before applying the optical flow algorithm to extract and monitor the up and down changes caused by respiration.

Convolutional Neural Network (CNN) can detect images from cameras installed on self-driving cars. First, we drove a car on a simulator and recorded frames from three cameras: left, right, and center. These frames were recorded at the rate of 30 frames per second. Additional data recorded were the distribution of steering angles, average velocity, etc. were passed through a CNN to train a self-driving system.

This paper presents a visual feedback control algorithm for a system using in the green house to monitor and diagnose health of vegetable in a garden. Firstly by using image processing, the position of a vegetable will be positioned. Secondly by using PD controller and continuously updating the position of vegetable, the PD image based visual serving (PDIBVS) algorithm is applied to move the camera to that vegetable location helping the system to track and diagnose their health.

Medical infrared thermal imaging (MITI) is a non-invasive imaging modality gaining popularity in the veterinary field. An infrared camera captures emission of heat and creates a color map in the form of a thermogram. Topical heat emission is influenced by localized disease processes as a result of autonomic nervous system imbalance.

Based on the operation time of the camera's optical sensor system including shutter time (ST) and sensor operating time, the accuracy of vehicle speed detection on highways as well as inner city streets can be significantly improved. The operation time of the camera’s sensor is essential for determination of frames over time in a vehicle surveillance system. Therefore, control of the shutter time ST will help a camera-based speed detection system to achieve much better accuracy

The paper presents a simple and efficient method of calibration for a camera-on-hand system, where the internal and external parameters of a 2D camera as well as the hand-eye parameters are simultaneously calibrated. The method is based on the 3D-to-2D projections of a calibrationblock with minimum two pure translations and two pure rotations of hand motions. Being evaluated on simulation data and real robot vision system indicate that our method can work stably with different noise and number of stations.
