Car: Computerized assistant referee for determining the offside rule in soccer by using computer vision

. In this document, we present a methodology in order to create an assistant for determining the offside using computer vision from processes of segmentation and object detection from captured using a webcam pictures which was within a space of controlled lighting. Thus, obtaining an image of the field in which the elements that are in it, and the distances they occupy within the image to thereby obtain the existence of offside is determined. For this approach, possibility is to know the theoretical elements necessary to determine the offside-rule in soccer, as well as the principles of computer vision necessary to perform image capture, segmentation and object detection as well as the tools necessary for its implementation.
