MATLAB (Matrix Laboratory)
MATLAB is a software and a package to implement signal processing. Using this tool one can create and test various signals & systems. These signals and systems can be tested for various parameters and operations. The real time simulation of signals, images, audio and video are performed using MATLAB. Various programs, syntax, applications and uses of MATLAB and signal processing can be discussed in this category. As the need for signal processing is increasing day by day, there is a need for separate category.

How do you implement svm algorithm in matlab?
There is a lot of information on the net about SVMs, and some matlab toolboxes contain the implemented code (i.e. SPIDER). Also look into "svmclassify and svmtrain" on matlab which seems to be a part of the Bioinformatics Toolbox. You can find good tutorials on VC Dimension and SVMs at http://www.autonlab.org/tutorials If you want to look at some brief matlab code, check out:
Technical Report: "Support Vector Machines for Classification and Regression" by Steve R. Gunn from the University of Southampton (1998).
What is a capture system image?
Can be captured locally or remotely using special software. Write-block the computer or device in question. Protects the acquisition target from being tainted during acquisition.
"Live" USB or CD/DVD can be used to boot and write protect the target computer. Computer OS is contained on USB or CD/DVD and loaded in RAM. Nothing is written to the hard disk of the target computer.
Make multiple copies of the imaged data. Use copies to perform the investigation and analysis. Never use the actual target hard drive(s).
Forensic software will log and timestamp every action taken during the investigation. Build a "case folder" to aid in documentation and reporting. Documentation is very important if needed for later recall, testimony, etc.
What are the Basic steps of Image Processing System?
1. Image acquisition
2. Image restoration/enhancement
3. Image segmentation
4. Image interpretation
How do you add a watermark to a digital image?
How To Add Watermark To A Digital Image: It's relatively easy if you have the software program (it will instruct you step-by-step.) There are so many different software's you will have to go onto: www. google.com to decide which one is right for you. Type in: Software for watermarking digital imagery. This will enable you to watermark ANYTHING and just not digital images. There are two types of watermark one that is visible and another the is invisible :)Also you can add watermark to protect image or to protect important image hidden inside normal image. I use Aoao Photo Watermark Software for protecting my images by visible watermarks: http://www.aoaophoto.com/
In image processing what is the basic relationship between pixels?
Neighborhood
adjacency
cnnectivity
paths
regions and boundaries
Matlab program for FM demodulation?
Matlab has a built-in function called "demod" in the communications (signal processing) toolbox where you can specify 'fm' for frequency demodulation.
An image in literature is the representation in language of how something looks, sounds, feels, smells, or tastes--the five senses. A gustatory image gives the reader an impression of taste: "Plums are delicious, / Both tart and sweet ...."
Top-down processing can be best described as?
perceiving what is shown in an image and then looking at individual pieces of it.
What are the practical applications of the emitter follower?
See an analog design textbook for some specific examples but the gist of emitter follower's purpose in life is to transform a high output resistance signal source to achieve a signal with lower output resistance.
making false attachment to an image is tampering
a take for granted if u want to change the head of a person and fit another persons head then it is called as tampering
How can you add an image to Google images?
its all robots that crawl the internet based on searches and prefrences (if nobody searched anything about Mario and didnt do stuff about Mario there wouldn't be images)
******ALL BASED ON GUESS******
(i saw the answer before and figured his was rubbish... "yes" lol hope this is correct and helps)
When some people screw up by secretly taking pictures (like on google to make it relevant) plus audio video raping their own sibling and ex friend and they ask the victims to pretend it doesn't exist and the family pervert continues to do it and mock them too while asking them to stick their head in the sand is as stupid as ignoring or pretending that family didn't steal private personal data and firearms from other family members as if one were to "just forget it or pretend it didn't happen" that it would go away and that's as foolish as playing a deadly game to the bloody bitter end isn't it so don't you see how it could have ONLY ONE END possible?
What are best courses which have best scope in future and easy to handle?
The best course to study is the one that leads to your overall career goals and objectives. Thus, I would imagine you do not have anything specific at this time. So many individuals enroll in college programs without a specific goal in mind. As such, many become miserable in their work which is not good for them, or their employer. If you want to be successful in your work and personal life, carefully consider the following.
To be successful in your work, you must acquire a vision. A vision is a clearly articulated picture of the future you intend to create for yourself. In other words, it's a dream. However, if the dream does not have direction, it will always remain a dream and will never become a reality for you. That vision should create a passion within you, a love for what you do and the benefit it will bring to others as well as yourself. Make sure the vision is specific, measurable, attainable, realistic, and tangible. Let us look at this closer. When you believe you have chosen an appropriate career goal, look at it in SMART fashion as follows. * Specific - Make sure your career goal is very specific. For example, "I would like to be a teacher," is not specific. "I would like to be a high school biology teacher in New Jersey (USA) in an urban school by 2012" is. * Measurable - Make sure you can measure your progress. How will I know I am progressing in the right direction? This is where the development of short-term objectives comes in (discussed below). You will know you are on the right path as you accomplish each short -term objective. * Achievable - Is the goal achievable considering my current life situation and circumstances? * Realistic - Is what I want to do really realistic. For example, "I would like to be a middle weight boxing champion, and I am 63 years old." That is not realistic. * Tangible - What will I - specifically - have at the end? What will I be (exactly)? It must be very specific. Once you acquire that vision your path will become clear. Still, you will need a mentor, counselor, or coach who will be able to help you develop a road map embedded with short-term objectives leading to your overall career goals and objectives. The achievement of short-term objectives will indicate you are moving in the correct direction, and will also give you energy and excitement to carry on towards your overall career goal. It will take some research, but you most likely have some ideas already. Follow them through, look at the nature of the field, the everyday routine, the required education, the salary, the occupational demand and the related fields. When a career sparks an interest, try to shadow an individual who is actually doing what you think you might like to do. You can pick up valuable information this way. Thus, the following. * Acquire the will to change circumstances. * Acquire the vision (dream). * Develop a road-map embedded with short-term objectives leading to your overall goal and objective. * Just do it and do not let go until it becomes a reality.
How do you do look-up table in MATLAB?
The "MathWorks" website contains all the code required to execute a look-up table in MATLAB. The site also contains hints and tips on documentation as well as a troubleshooter facility.
Ppt presentations on new technologies using image processing?
PowerPoint presentations on new technologies using image processing are quite advanced. They are able to bring out shapes in 3D format and offer compensation for defects in image processing.
What are brightness and contrast in image processing?
Brightness and contrast represent a way to adjust an image. They come from the display technology, being common controls in all monitors.
The color brightness/contrast are similar to the grayscale counterparts, in most cases being applied to all channels (even if from the physical point of view this is wrong - a transformation into HSI with adjustment of the I component would be correct -.
For a grayscale image, brightness represents an image adjustment where a constant value is added to all pixel values.
The contrast adjustament is a multiplication of the pixel values with a constant.
Most of the image processing programs use a different scale, for example from 0 to 10. If you wish to experiment with it, you can do it photoshop, gimp. To apply a brightness/contrast correction to a bunch of images is easier with an image converter like AZImage - see related link.
How do you find flat region in digital image processing?
You could calculate two perpendicular gradients to each image pixel point. If both gradient are small the pixel pertains to a flat region.
What is angular second moment in digital image processing?
This feature is a measure of the smoothness of the image.
How Gaussian filter is used in image processing?
Gaussian Blur blurs image but you can use it to soften mask edges and to create different effects like Glamour glow.
