RGB conversion in matlab


Generating RGB image
RGB concept:
An RGB image, sometimes referred to as a truecolor image, is stored as an m-by-n-by-3 data array that defines red, green, and blue color components for each individual pixel. RGB images do not use a palette. The color of each pixel is determined by the combination of the red, green, and blue intensities stored in each color plane at the pixel's location. Graphics file formats store RGB images as 24-bit images, where the red, green, and blue components are 8 bits each. This yields a potential of 16 million colors. The precision with which a real-life image can be replicated has led to the nickname “truecolor image.”
Code description:
Zeros();
X = zeros(n) returns an n-by-n matrix of zeros
Create array of all zeros
Cat concept:
Concatenate arrays along specified dimension
Here is source code

Image compression in matlab with explaination

Image
Image compression Wcompress command: The  wcompress  command performs either compression or uncompression of grayscale or truecolor images. Spiht parameter of wcompress: spiht' Set Partitioning In Hierarchical Trees Xc = wcompress( 'u' , 'wpeppers.wtc' ); uncompresses the file  SAV_FILENAME , which contains the compressed image, and returns the image  XC . Depending on the initial compressed image,  XC  can be a 2-D array containing either an indexed image or a 3-D array of  uint8  containing a truecolor image. [CR,BPP] = wcompress( 'c' ,X, 'wpeppers.wtc' , 'spiht' , 'maxloop' ,12); [COMPRAT,BPP] = wcompress('c',...)  returns the compression ratio  COMPRAT  and the bit_per_pixel ratio  BPP .` Comprat  states the compression ratio ‘ BPP'  =  'bpp'  or  'BPP'  sets the bit-per-pixel ratio. 'c'  : color transformation type (RGB  uint8 ). axis...

Data Types in Matlab

  MATLAB does not require any type declaration or dimension statements. Whenever MATLAB encounters a new variable name, it creates the variable and allocates appropriate memory space. If the variable already exists, then MATLAB replaces the original content with new content and allocates new storage space, where necessary. For example, Total = 42 The above statement creates a 1-by-1 matrix named 'Total' and stores the value 42 in it. Data Types Available in MATLAB MATLAB provides 15 fundamental data types. Every data type stores data that is in the form of a matrix or array. The size of this matrix or array is a minimum of 0-by-0 and this can grow up to a matrix or array of any size. The following table shows the most commonly used data types in MATLAB − Sr.No. Data Type & Description 1 int8 8-bit signed integer 2 uint8 8-bit unsigned integer 3 int16 16-bit signed integer 4 uint16 16-bit unsigned integer 5 int32 6 uint32 32-bit unsigned integer 7 int64 64-bit signed integer...

Face detection in Matlab with source code

Image
Face Detection Object detection and tracking are important in many computer vision applications, including activity recognition, automotive safety and surveillance. Presented here is an face detection using MATLAB system that can detect not only a human face but also eyes and upper body. Face detection is an easy and simple task for humans, but not so for computers. It has been regarded as the most complex and challenging problem in the field of computer vision due to large intra-class variations caused by the changes in facial appearance, ligh ting and expression. Such variations result in the face distribution to be highly nonlinear and complex in any space that is linear to the original image space. Face detection is the process of identifying one or more human faces in images or videos. It plays an important part in many biometric, security and surveillance systems, as well as image and video indexing systems. WHAT IS FACE DETECTION? The definition of face dete...
