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.

The Average (mean) filter smooths image data, thus eliminating noise. This filter performs spatial filtering on each individual pixel in an image using the grey level values in a square or rectangular window surrounding each pixel. For example: a1 a2 a3 a4 a5 a6 3x3 filter window a7 a8 a9 The...
d = det(X) returns the determinant of the square matrix X . If X contains only integer entries, the result d is also an integer. The determinant is computed from the triangular factors obtained by Gaussian elimination[L,U] = lu(A) s = det(L) % This is always +1 or -1 det(A) = s...

Matlab has a lot of functions for interpolate, depending on what you're trying to do. You don't need a toolbox for it, either. Type "doc interp1" to get started and navigate the help file from there.
Image Processing classify as three type. (1) Low level image processing (noise removal, image sharpening, contrast enhancement) (2) Mid level image processing (segmentation) (3) High level image processing (analysis based on output of segmentation)
Digital Image Processing is a type of Digital manipulation pertaining to pictures and video. "Photoshopping" a digital picture is an example of Digital Image Processing. Another example is what takes place in a digital camera when the image is captured on the image sensor and converted into a JPEG...
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...
For a grayscale image, brightness represents an image adjustment where a constant value is added to all pixel values shifting the grayscale curve on the y axis.
MATLAB has a number of advantages over other methods or languages: . Its fundamental data element is the matrix. A straightforward integer is measured an matrix of one row and one column. Several mathematical operations that work on arrays or matrices are built-in to the Matlab environment. For...

Excel is considerably easier to learn, but is very limited in its data analysis and graphics. MATLAB has a very steep learning curve, but can do anything you want. Seriously, anything. If this is part of your work or research, I highly recommend learning MATLAB.

There have been many technological advancements over the years.Amazing processing speeds, quality, controls, and print methods areamong the advancements we use today.
no, google is a search engine all it does is search for websites that have some words in common to your search and find the sites that have images
Resolution has quality of images and their purpose. Resolution is measured with pixels, more pixels, more details on the image, also for printing you need usually 300 pixels per inch and for web 72-96 is enough.
A mask is a black and white image of the same dimensions as the original image (or the region of interest you are working on). Each of the pixels in the mask can have therefore a value of 0 (black) or 1 (white). When executing operations on the image the mask is used to restrict the result to the...
Just save it in format zou want, you can do that from File - Save , Save as, Save for Web and Devices
Many programming languages do the same. Note that you can extend the range, simply by multiplying by some number. For example, if you want a random number between 0 and 10, multiply the random number by 10.

You could calculate two perpendicular gradients to each image pixel point. If both gradient are small the pixel pertains to a flat region.

That is a trade-off that the end user has to decide. Compression reduces size which saves space on a disk (including within a document) and cuts time while sending and doing backups. You have to look at how the photo will be viewed and decide how much distortion of the image is noticeable and how...
Saliency is an attempt to determine which regions of an image are the most conspicuous. It's a loosely bio-inspired concept - when processing a new scene a low-level process drives rapid eye movement (called saccades) as the brain seeks to determine what it needs the eyes to focus on first. This...

Matlab is a language and package as well. The language used in Matlab tool is Matlab. Matlab itself is a language. Matlab is a package. Matlab is a tool. Its an all in one.
Digital image processing is great because you can save a filedigitally and it can be uploaded in a matter of seconds. Adisadvantage is that some may edit their photos instead of takinghigh quality photographs.
Alternative Current has both negative voltage and positive voltage and that are phases that it must go trough to complete one cycle, A bridge rectifier is nothing more then a rectifier that ac tally rectify both +/- phases to give out pulsating Direct Current of either polarity if wanted.
This following loop creates a unit ramp input : for t= 0:0.1:5 if(t1) y(count) = 1; end Rz(count) = tf(y(count)*T,[1 -2 1],T); Rs(count) = d2c(Rz(count)); end % T = 0.005; this is for a discrete system

One of the main advantages of Simulink is the ability to model a nonlinear system, which a transfer function is unable to do. Another advantage of Simulink is the ability to take on initial conditions.
This command looks for object edges, object edges or any edges are determined wit difference between neighboring pixels.

Do you mean on a piece of paper? If so, you have to add perspective to it. One way to do that is to draw a background. Another way is to give your object a 3D illusion through techniques such as shadowing and shading.
You can do this by selecting the sequence of images you want to animate and then using the Matlab's function called "im2frame". This will result in a video.

The four major areas of computer operations in digital image processing is contrast enhancement. The second is remove the blur from pictures and smooth out graininess. The third would be magnifying, and rotating an image. Finally the image is compressed for storage.
An image is called real if the light rays coming from a point(point on object) meet at a point after reflection or refraction. An image is virtual if the light rays do not actually meet after reflection or refraction. These rays appear to come from a point which is the point where we say virtual...
