Final Report on
Dual-Tone Multiple Frequency (DTMF) Detector Implementation
Presented By:
Giiner Arslan
for EE382C Embedded Software Systems
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

Skin Tone based Secret Data hiding in Images


Presented by:
B.Rajendraprasad

abstract
 Here secret data is embedded within skin region of image that will provide an excellent secure location for data hiding. For this skin tone detection is performed using HSV (Hue, Saturation and Value) color space. Additionally secret data embedding is performed using frequency domain approach - DWT (Discrete Wavelet Transform), DWT outperforms than DCT (Discrete Cosine Tr..............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:
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
Organic electronics, (plastic electronics or polymer electronics), deals with conductive polymers, plastics, or small molecules. It is called 'organic' electronics because the polymers and small molecules are carbon-based, like the molecules of living things. This is as opposed to traditional electronics (or metal electronics) which relies on inorganic conductors such as copper or silicon. Polymer electronics are laminar electronics
