چکیده
1.2 Detection task For each of the four classes predict the bounding boxes of each object of that class in a test image (if any). Each bounding box should be output with an associated real-valued confidence of the detection so that a precision/recall curve can be drawn. To be considered a correct detection, the area of overlap ao between the predicted bounding box Bp and ground truth bounding box Bgt must exceed 50% by the formula: ao = area(Bp ∩Bgt) area(Bp ∪Bgt) (1)

Pascal Visual Object Classes Challenge Results
The goal of this challenge is to recognize objects from a number of visual object classes in images of realistic scenes. It is fundamentally a supervised learning learning problem in that a training set of labelled images is provided. The object classes are: motorbikes, bicycles, people and cars. Twelve participants entered the challenge. A full description of the challenge including software a...
متن کاملThe 2005 PASCAL Visual Object Classes Challenge
The PASCAL Visual Object Classes Challenge ran from February to March 2005. The goal of the challenge was to recognize objects from a number of visual object classes in realistic scenes (i.e. not pre-segmented objects). Four object classes were selected: motorbikes, bicycles, cars and people. Twelve teams entered the challenge. In this chapter we provide details of the datasets, algorithms used...
متن کاملThe Pascal Visual Object Classes Challenge 2006 (VOC2006) Results
This report presents the results of the 2006 PASCAL Visual Object Classes Challenge (VOC2006). Details of the challenge, data, and evaluation are presented. Participants in the challenge submitted descriptions of their methods, and these have been included verbatim. This document should be considered preliminary, and subject to change.
متن کاملLinear combinations of simple classifiers for the PASCAL challenge
Our class project for the 16–721 Advanced Perception was an entry in the PASCAL Visual Object Classes Challenge 2006. The goal of this challenge is to determine whether an object from one of ten classes appears in a given image. Labelled training data was provided, and participants were free to use any method. We chose to implement a bag–of–words classifier using color, shape, and texture infor...
متن کاملImage Segmentation for Object Detection using CRFs with Robust Higher Order Clique Potentials
Object recognition is a fundamental problem in computer vision. In this work, an approach for object recognition that combines detection and segmentation is explored. Using the result of segmentation in the detection process leads to significant improvements in the recognition accuracies. Rather than considering a simple pairwise CRF model for the segmentation process, the use of higher-order c...
