APPROVED ABSTRACTS

1. DIGITAL IMAGE PROCESSING (Sreehari. B, Anit Joseph)

Approved by Mr.Sunish

Digital image processing is the use of computer algorithms to perform image processing on digital images. Digital image processing has the same advantages over analog image processing as digital signal processing has over analog signal processing — it allows a much wider range of algorithms to be applied to the input data, and can avoid problems such as the build-up of noise and signal distortion during processing. The most common kind of digital image processing is digital image editing.

2. BLUETOOTH (Shameer. A, Noble.K)

Approved by Mr.Akash

Bluetooth is an industrial specification for wireless personal area networks (PANs). Bluetooth provides a way to connect and exchange information between devices such as mobile phones, laptops, personal computers, printers, digital cameras, and video game consoles over a secure, globally unlicensed short-range radio frequency. The Bluetooth specifications are developed and licensed by the Bluetooth Special Interest Group

3. ANIMATION (Gayathri. A, Shereen. J)

Approved by Mrs.Jassia

Animation is the rapid display of a sequence of images of 2-D artwork or model positions in order to create an illusion of movement. It is an optical illusion of motion due to the phenomenon of persistence of vision, and can be created and demonstrated in a number of ways. The most common method of presenting animation is as a motion picture or video program, although several other forms of presenting animation also exist.

4 MULTIBAND LOUDNESS CORRECTION HEARING AIDS AND COCHLEAR IMPLANTS (Dona. P, Jyothi. E)

Approved by Ms. Sajithra

A cochlear implant (CI) is a surgically implanted electronic device that provides a sense of sound to a person who is profoundly deaf or severely hard of hearing. The cochlear implant is often referred to as a bionic ear. Unlike hearing aids, the cochlear implant does not amplify sound, but works by directly stimulating any functioning auditory nerves inside the cochlea with electrical impulses. External components of the cochlear implant include a microphone, speech processor and transmitter which also allows an individual to adjust the sound for quality and amplification.

DIGITAL IMAGE PROCESSING

Digital image processing is the use of computer algorithms to perform image processing on digital images. Digital image processing has the same advantages over analog image processing as digital signal processing has over analog signal processing — it allows a much wider range of algorithms to be applied to the input data, and can avoid problems such as the build-up of noise and signal distortion during processing. The most common kind of digital image processing is digital image editing.

Digital processing of camera images

Digital cameras generally include dedicated digital image processing chips to convert the raw data from the image sensor into a color-corrected image in a standard image file format. Images from digital cameras often receive further processing to improve their quality, a distinct advantage digital cameras have over film cameras. The digital image processing is typically done by special software programs that can manipulate the images in many ways.

Many digital cameras also enable viewing of histograms of images, as an aid for the photographer to better understand the rendered brightness range of each shot.

Uses

Digital Image Processing allows the use of much more complex algorithms for image processing, and hence can offer both more sophisticated performance at simple tasks, and the implementation of methods which would be impossible by analog means.

Some techniques which are used in digital image processing include:

Principal components analysis

Independent component analysis

Self-organizing maps

Hidden Markov models

Neural networks

BLUETOOTH TECHNOLOGY

Bluetooth is an industrial specification for wireless personal area networks (PANs). Bluetooth provides a way to connect and exchange information between devices such as mobile phones, laptops, personal computers, printers, digital cameras, and video game consoles over a secure, globally unlicensed short-range radio frequency. The Bluetooth specifications are developed and licensed by the Bluetooth Special Interest Group.

Uses

Bluetooth is a standard and communications protocol primarily designed for low power consumption, with a short range (power-class-dependent: 1 meter, 10 meters, 100 meters) based on low-cost transceiver microchips in each device.

Bluetooth enables these devices to communicate with each other when they are in range. The devices use a radio communications system, so they do not have to be in line of sight of each other, and can even be in other rooms, as long as the received transmission is powerful enough.

List of applications

A typical Bluetooth mobile phone headset. More prevalent applications of Bluetooth include:

1.      Wireless control of and communication between a mobile phone and a hands-free headset. This was one of the earliest applications to become popular.

2.      Wireless networking between PCs in a confined space and where little bandwidth is required.

3.      Wireless communications with PC input and output devices, the most common being the mouse, keyboard and printer.

4.      Transfer of files between devices with OBEX.

5.      Transfer of contact details, calendar appointments, and reminders between devices with OBEX.

6.      Replacement of traditional wired serial communications in test equipment, GPS receivers, medical equipment, bar code scanners, and traffic control devices.

7.      For controls where infrared was traditionally used.

8.      Sending small advertisements from Bluetooth enabled advertising hoardings to other, discoverable, Bluetooth devices.

9.      Dial-up internet access on personal computer or PDA using a data-capable mobile phone as a modem

ANIMATION

Animation is the rapid display of a sequence of images of 2-D artwork or model positions in order to create an illusion of movement. It is an optical illusion of motion due to the phenomenon of persistence of vision, and can be created and demonstrated in a number of ways. The most common method of presenting animation is as a motion picture or video program, although several other forms of presenting animation also exist.

Computer animation

 Like stop motion, computer animation encompasses a variety of techniques, the unifying idea being that the animation is created digitally on a computer.

2D animation

Figures are created and/or edited on the computer using 2D bitmap graphics or created and edited using 2D vector graphics. This includes automated computerized versions of traditional animation techniques such as of tweening, morphing, onion skinning and interpolated rotoscoping. Egs.

 ·        Foster's Home for Imaginary Friends, Jib Jab, Mickey the Squirrel

 ·        Analog computer animation

 ·        Flash animation

 ·        PowerPoint animation

 3D animation

Digital models manipulated by an animator. In order to manipulate a mesh, it is given a digital armature (sculpture). This process is called rigging. Various other techniques can be applied, such as mathematical functions (ex. gravity, particle simulations), simulated fur or hair, effects such as fire and water and the use of Motion capture to name but a few. Many 3D animations are very believable and are commonly use as special effects for recent movies. Examples:

 ·        The Incredibles, Shrek, Finding Nemo

3D animation Terms

Cell-shaded animation

Morph target animation

Skeletal animation

MULTIBAND LOUDNESS CORRECTION HEARING AIDS AND COCHLEAR IMPLANTS

A cochlear implant (CI) is a surgically implanted electronic device that provides a sense of sound to a person who is profoundly deaf or severely hard of hearing. The cochlear implant is often referred to as a bionic ear. Unlike hearing aids, the cochlear implant does not amplify sound, but works by directly stimulating any functioning auditory nerves inside the cochlea with electrical impulses. External components of the cochlear implant include a microphone, speech processor and transmitter which also allows an individual to adjust the sound for quality and amplification.

Individuals who have acquired deaf blindness (loss of hearing and vision combined) may find cochlear implants a radical improvement in their daily life. It may provide them with more information for safety, communication, balance, orientation and mobility and promote interaction within their environment and with other people, reducing isolation. Having more auditory information that they may be familiar with may provide them independent gathering of information to become more independent.

The implant often gives recipients additional auditory information, which may include sound discrimination fine enough to understand speech in quiet environments. Though sufficient, and quality, post-implantation rehabilitative therapy is a critical factor affecting the success rate.

Parts of the cochlear implant

The implant is surgically placed under the skin behind the ear. The basic parts of the device include:

External:

A microphone which picks up sound from the environment a speech processor which selectively filters sound to priorities audible speech and sends the electrical sound signals through a thin cable to the transmitter,

A transmitter, which is a coil held in position by a magnet placed behind the external ear, and transmits the processed sound signals to the internal device by electromagnetic induction,

Internal:

A receiver and stimulator secured in bone beneath the skin, which converts the signals into electric impulses and sends them through an internal cable to electrodes,

An array of up to 22 electrodes wound through the cochlea, which send the impulses to the nerves in the scala tympani and then directly to the brain through the auditory nerve system.
