1. 6. An early fire detection system through registration and analysis of waste station IR-images

   University essay from Datorseende

   Author : Rikard Söderström; [2011]
   Keywords : KLT; Track-Retrack; RANSAC; MSER; ROC; Registration; Image Processing;

   Abstract : In this thesis, an investigation was performed to find ways of differencing between firesand vehicles at waste stations in hope of removing vehicles as a source of error duringearly fire detection. The existing system makes use of a heat camera, which rotates in 48different angles (also known as zones) in a fixed position. READ MORE
