Flame Detection Using Appearance-Based Pre-Processing and Convolutional Neural Network

open access: yesApplied Sciences, 2021
It is important for fire detectors to operate quickly in the event of a fire, but existing conventional fire detectors sometimes do not work properly or there are problems where non-fire or false reporting occurs frequently. Therefore, in this study, HSV

Performance Assessment of Feature Detection Algorithms: A Methodology and Case Study on Corner Detectors [PDF]

open access: yes, 2003
In this paper we describe a generic methodology for evaluating the labeling performance of feature detectors. We describe a method for generating a test set and apply the methodology to the performance assessment of three well-known corner detectors: the

Improved Harris' Algorithm for Corner and Edge Detections

open access: yes2007 IEEE International Conference on Image Processing, 2007
A more accurate algorithm for corner and edge detections that is the improved form of the well-known Harris' algorithm is introduced. First, instead of approximating |L[m+x, n+y]-L[m, n]|2 just in terms of x2, xy, and y2, we will approximate |L[m+x, n+y]-L[m, n]|(L[m+x, n+y]-L[m, n]) by the linear combination of x2, xy, y2, x, y, and 1.
