Segmentation in live video in MatLab

Here is model for face detection. Bounding box is to track and detect face. Active contours need to be added to get exact shape of the face not its features. To do this we need to proceed with segmentation of the frames within the video. I applied…

Solving ODEs inside a Subsystem in Simulink

I'm trying to figure out how to solve a system of ODEs inside a subsystem in a Simulink model. Basically, each call to this subsystem, which happens at each tick of the simulation clock (fixed-step), entails solving the ODEs. So there's like a…

How to declare global variables for simulink containing matlab functions?

I'm building a Simulink model with multiple Matlab function blocks. Each of these function blocks has a lot of constants, for example, g = 9.8, common between them. I want to initialize all of these constants in one go so that I don't have to do so…
