### How to Implement Bitplane slicing in MATLAB?

AIM:  Study and Implementation of Bitplane Slicing in MATLAB.

THEORY:
Separating a digital image into its bit-planes is useful for analyzing the relative importance played by each bit of image, a process aids in determining the adequacy of the no. of bits used to quantize each pixel. This type of decomposition is useful for image compression. This term of bit-plane extraction for an 8 bit image, it is not difficult to show that the (binary) image for bit-plane 7 can be obtained by processing input image with a thresholding gray-level transformation function.

### Study of Read and write different types of images in MATLAB (Binary image, Grayscale image and Color image).

AIM: Read and write different types of images (Binary image, Grayscale image and Color image)

THEORY:

Basically image having three types
1) Binary image: Binary image is the image which having 1 bit/pixel. It has 1 bitplane. Minimum pixel value of image is 0 and maximum is 1.

### Basic Study of Graphical User Interface in MATLAB.

AIM: Study of Graphical User Interface in MATLAB.

THEORY:
Graphical user interface plays important role in today’s computer era. For user friendly operations we use graphical user interface. VB, .net these are some languages that we used for creating GUI. MATLAB provides us simple and user friendly graphical user interface tool named as ‘guide’.

### How to handle Video in MATLAB?

Video file reading in Matlab is interesting process. So aim of this experiments is
1. How to read video file in Matlab?
2. How to play video files in Matlab?
3. How to check size of the video file in Matlab?

### How to create user defined function in MATLAB?

AIM: Study and Implementation of user defined function.

THEORY:
MATLAB function is a special type of M-file that runs in its own independent workspace. It receives input data through an input argument list, and returns results to the caller through an output argument list.

### Study and Implementation of Branching Statements (if – else and Switch). Implementation of Finding Quadratic equation, Finding Even odd, Finding Greatest Number....

AIM: Study and Implementation of Branching Statements (if – else and Switch).
THEORY:
Decision making structures require that the programmer specify one or more conditions to be evaluated or tested by the program, along with a statement or statements to be executed if the condition is determined to be true, and optionally, other statements to be executed if the condition is determined to be false.

### Study and Implementation of Looping Statements (for loop and while loop), Implementation of Peak Signal to Noise Ratio and Factorial of Number.....

AIM: Study and Implementation of Looping Statements (for loop and while loop).

THEORY:
Loops are MATLAB constructs that permit us to execute a sequence of statements more than once. There are two basic forms of loop constructs: while loops and for loops. The major difference between these two types of loops is in how the repetition is controlled. The code in a while loop is repeated an indefinite number of times until some user-specified condition is satisfied. By contrast, the code in a “for loop” is repeated a specified number of times, and the number of repetitions is known before the loops starts.

### Study and Implementation of Discrete Time Signal and Continuous Time Signal using Stem and Plot Command Respectively.

AIM: Study and Implementation of Plot and Stem Command.
THEORY:
1. For ‘STEM’ Command:
A discrete time signal has a value defined only at discrete points in time in these signals the independent variables takes only a discrete set of integer values.
e.g. Attendance of students Vs date (time)
Representation of DT sequence:

### Study and Implementation of Matrix Manipulation and Array Handling.

AIM: Study and Implementation of Matrix Manipulation and Array Handling.
THEORY:
The fundamental unit of data in any MATLAB program is the array. An array is a collection of data values organized into rows and columns and known by a single name. Individual data values within an array are accessed by including the name of the array followed by subscripts in parentheses that identify the row and column of the particular value. Even scalars are treated as arrays by MATLAB—they are simply arrays with only one row and one column. Arrays can be classified as either vectors or matrices.
