The Selective Search software is made publicly available 1. 1 Introduction For a long time, objects were sought to be delineated before their identification.
ation of object recognition algorithms and in developing new techniques. Novel algorithmic innovations emerge with the availability of large-scale training data. The broad spectrum of object categories motivated the need for algorithms that are even able to distinguish classes which are visually very similar. We highlight the most
development of object classification, localization and detec-tion techniques. 2.1. Sliding Window In the early development of face detection, researchers tended to treat it as a repetitive task of object classifica-tion, by imposing sliding windows and performing object classification with the neural networks on the window re-gion.
human perception of the size of object keeps constant. The size of image on the human Open Access Database www.i-techonline.com retina directly depends on the distan ce between the object and our eyes.

Hence without prior recognition it is hard to decide that a face and a sweater are part of one object ( Tu et al. 2005). This has led to the opposite of the traditional approach: to do localisation through the identification of an object. This recent approach in object recognition has made enor-mousprogressinlessthanadecade(DalalandTriggs2005;
Fine-grained recognition tasks such as identifying the species of a bird, or the model of an aircraft, are quite challenging because the visual differences between the cat-egories are small and can be easily overwhelmed by those causedbyfactorssuchaspose,viewpoint,orlocationofthe object in the image. For example, the inter-category vari-
We present YOLO, a new approach to object detection. Prior work on object detection repurposes classifiers to per-form detection. Instead, we frame object detection as a re-gression problem to spatially separated bounding boxes and associated class probabilities. A single neural network pre-dicts bounding boxes and class probabilities directly ...
