TL;DR: A peak-tracking spectrum analyzer, called Parshl, which is useful for extracting additive synthesis parameters from inharmonic sounds such as the piano, based on the Short-Time Fourier Transform.
Abstract: This paper describes a peak-tracking spectrum analyzer, called Parshl, which is useful for extracting additive synthesis parameters from inharmonic sounds such as the piano. Parshl is based on the Short-Time Fourier Transform (STFT), adding features for tracking the amplitude, frequency, and phase trajectories of spectral lines from one FFT to the next. Parshl can be thought of as an “inharmonic phase vocoder” which uses tracking vocoder analysis channels instead of a fixed harmonic filter bank as used in previous FFT-based vocoders. This is the original full version from which the Technical Report (CCRMA STAN-M-43) and conference paper (ICMC-87) were prepared. Additionally, minor corrections are included, and a few pointers to more recent work have been added. Work supported in part by Dynacord, Inc., 1985

TL;DR: It is shown that increases in blood flow in inferior temporal regions are associated with object decisions about possible but not impossible objects, and that there are increases in the vicinity of the hippocampal formation associated with episodic recognition of possible objects.
Abstract: An object's global, three-dimensional structure may be represented by a specialized brain system involving regions of inferior temporal cortex1–3. This system's role in object representation can be understood by experiments in which people study drawings of novel objects with possible or impossible three-dimensional structures, and later make either possible/impossible object decisions or old/ new recognition decisions about briefly flashed studied and non-studied objects. Although object decisions about possible objects are facilitated by prior study, there is no corresponding facilitation for impossible objects, thereby implicating a system that is specifically involved in the representation of structurally coherent visual objects4. Here we show, by positron emission tomography (PET), that increases in blood flow in inferior temporal regions are associated with object decisions about possible but not impossible objects, and that there are increases in the vicinity of the hippocampal formation associated with episodic recognition of possible objects.

19 Sep 2006TL;DR: In this paper, the authors present a system that facilitates shopping for a tangible object via a network using a mobile device, where a graphical representation of a scene of a local environment using a sensor of the mobile device is obtained via the network.
Abstract: Facilitating shopping for a tangible object via a network using a mobile device involves obtaining a graphical representation of a scene of a local environment using a sensor of the mobile device. Graphical object data that enables a three-dimensional representation of the tangible object to be rendered on the mobile device is obtained via the network, in response to a shopping selection. The three-dimensional representation of the tangible object is displayed with the graphical representation of the scene via the mobile device so that the appearance of the tangible object in the scene is simulated.
