Object Activity Scene Description, Construction, and Recognition

Nonparametric Object and Scene Recognition

With the advent of the Internet, billions of images are now freely available online and constitute a dense sampling of the visual world. Using a variety of nonparametric methods, we explore this world with the aid of a large data set of 79,302,017 images collected from the Web. Motivated by psychophysical results showing the remarkable tolerance of the human visual system to degradations in ima...

Object Recognition by Scene Alignment

Current object recognition systems can only recognize a limited number of object categories; scaling up to many categories is the next challenge. We seek to build a system to recognize and localize many different object categories in complex scenes. We achieve this through a simple approach: by matching the input image, in an appropriate representation, to images in a large training set of labe...

Non-commercial Object-Base Scene Description

This paper investigates the development of a non-commercial object-based scene description language, for the effective capture of twoand three-dimensional scenes. Design science research techniques were applied to determine the factors involved in effective scene capture. The solution facilitates the description of 2D and 3D environments via interpretation of object relationships; the implement...

Object-based Audio Reproduction and the Audio Scene Description Format

The introduction of new techniques for audio reproduction such as HRTF-based technology, wave field synthesis and higher-order Ambisonics is accompanied by a paradigm shift from channel-based to object-based transmission and storage of spatial audio. Not only is the separate coding of source signal and source location more efficient considering the number of channels used for reproduction by la...
