Automatic Generation of Image Identifiers Based on Luminance and Parallel Processing

Accessibility of speech information in videos is a huge challenge for the hearing impaired, making a visual representation such as text subtitling essential. Unavailability of a good Automatic Speech Recognition (ASR) engine, makes automatic generation of text subtitles for resource deficient languages such as Indian languages, extremely difficult. Techniques to build such an ASR using audio and corresponding transcription in the form of broadcast news or audio books have been proposed; however, these techniques require transcriptions corresponding to the audio in editable text format, which are unavailable for resource deficient languages. In this chapter, a novel technique of building a sound-glyph database for a resource deficient language has been described. The sound-glyph database can be used effectively to subtitle videos in the same language script. Considering large volumes of data that need to be processed, we propose a parallel processing method in a multiresolution setup, harnessing the multi-core capacity of present day computers.

Abstract. The Simon effect lies on the automatic generation of a stimulus spatial code, which, however, is not relevant for performing the task. Results typically show faster performance when stimulus and response locations correspond, rather than when they do not. Considering reaction time distributions, two types of Simon effect have been individuated, which are thought to depend on different mechanisms: visuomotor activation versus cognitive translation of spatial codes. The present study aimed to investigate whether the presence of a distractor, which affects the allocation of attentional resources and, thus, the time needed to generate the spatial code, changes the nature of the Simon effect. In four experiments, we manipulated the presence and the characteristics of the distractor. Findings extend previous evidence regarding the distinction between visuomotor activation and cognitive translation of spatial stimulus codes in a Simon task. They are discussed with reference to the attentional model of the Simon effect.
