Abstract:
The natural world presents our visual system with a wide range of colours and intensities. A starlit night has an average luminance level of around 10-3 candelas/m2, and daylight scenes are close to 105 cd/m2.
Humans can see detail in regions that vary by 1:104 at any given adaptation level, over which the eye gets swamped by stray light (i.e., disability glare) and details are lost. Modern camera lenses, even with their clean-room construction and coated optics, cannot rival human vision when it comes to low f ....etc

Abstract”

In this work we propose a method to identify the raga of a Carnatic music signal. Raga is analogous to melody in Western music but is much richer and stronger in its representation. The main motive behind Raga identification is that it can be used as a good basis for music information retrieval of Carnatic music songs or Film songs based on Carnatic music. The input polyphonic music signal is analyzed and made to pass through a signal separation algorithm to separate the instrument and the vocal signal. After extracting the ....etc

SYNOPSIS
Dual-tone Multi-Frequency (DTMF) signaling is the basis for voice communications control and is widely used worldwide in modern telephony to dial numbers and configure switchboards. It is also used in systems such as in voice mail, electronic mail and telephone banking.
The detector part of early DTMF systems consisted of analog implemented bandpass filter banks, which were tuned to the eight standard frequencies. As analog lines as well as many other analog systems were converted to digital, researchers became ....etc

Abstract
Dual-tone Multi-frequency (DTMF) signals are used in touch-tone telephones as well as many other areas such as interactive control, telephone banking, and pager system. As analog telephone lines are converted to digital, researchers became interested in digital DTMF detectors.
There are many digital DTMF detecting algorithms, but most of them do not comply wit ....etc
