The aim of this work is to describe a computer system to detect and measure the pupil and iris size with applications to dynamic pupillometry. The system was written using the OpenCV library to perform the real time video processing. The frames are captured in grayscale and processed using normalization and threshold techniques to enhance the image, and(More)
This paper describes the design of a hardware based system to locate and measure the pupil size using FPGA. The system was implemented in a Cyclone 4E EP4CE115F29C7, from Altera. The component has 114,480 logic elements, although only 8% of the component was used. To detect the pupil the system uses the Greedy Snakes Algorithm at 50 MHz input clock. The(More)
The objective of this project is to design and develop a multi-conference and multi-platform application for phones as an m-health system, to improve the communication between healthcare providers and healthcare recipients, to eliminate the obstacles of distance, providing faster and specialized services to people living in remote areas. There is a variety(More)
One of the determining factors for the correct execution of resistance training (RT) is the determination of the resistance, the fatigue generated by the resistance has a direct relation to the execution speed of the exercise. This work aims designing and testing a system to measure the execution speed of the exercise in RT using an accelerometer. The(More)
