Conformance test of simple profile MPEG-4 texture decoding
Moving picture experts group (MPEG)-4 visual conformance standard specifies methods to verify whether bitstreams and decoders meet the requirements at a specified profile and level. The test of decoders can be divided into two parts: static and dynamic tests. The static test can be performed by comparing images from a decoder under test with those from a reference decoder using various test bit...
متن کاملFunctional specificity of rat vibrissal primary afferents
In this study, we propose to analyze the peripheral vibrissal system specificity through its neuronal responses. Receiver operating characteristics (ROC) curve analyses were used, which required the implementation of a binary classifier (artificial neural network) trained to identify the applied stimulus. The training phase consisted of the observation of a predetermined amount of vibrissal swe...
متن کاملEncoding of Vibrissal Active Touch
Mammals acquire much of their sensory information by actively moving their sensory organs. Yet, the principles of encoding by active sensing are not known. Here we investigated the encoding principles of active touch by rat whiskers (vibrissae). We induced artificial whisking in anesthetized rats and recorded from first-order neurons in the trigeminal ganglion. During active touch, first-order ...
متن کاملBiomimetic vibrissal sensing for robots.
Active vibrissal touch can be used to replace or to supplement sensory systems such as computer vision and, therefore, improve the sensory capacity of mobile robots. This paper describes how arrays of whisker-like touch sensors have been incorporated onto mobile robot platforms taking inspiration from biology for their morphology and control. There were two motivations for this work: first, to ...
متن کاملTemporal Decoding by Phase-Locked Loops: Unique Features of Circuit-Level Implementations and Their Significance for Vibrissal Information Processing
Rhythmic active touch, such as whisking, evokes a periodic reference spike train along which the timing of a novel stimulus, induced, for example, when the whiskers hit an external object, can be interpreted. Previous work supports the hypothesis that the whisking-induced spike train entrains a neural implementation of a phase-locked loop (NPLL) in the vibrissal system. Here we extend this work...
