Arithmetic and Logical Operations on Images (Image Algebra) These operations are applied on pixel-by-pixel basis. So, to add two images together, we add the value at pixel (0 , 0) in image 1 to the value at pixel (0 , 0) in image 2 and store the result in a new image at pixel (0 , 0). Then we move to the next pixel and repeat the process, continuing until all pixels have been visited.
An image must be converted to numerical form before processing. This conversion process is called digitization, and a common form is illustrated in Figure (1). The image is divided into small regions called picture elements, or pixel for short. The most common subdivision scheme is the rectangular sampling grid shown in Figure (1). The image is divided into horizontal lines made up of adjacent pixels. At each pixel location, the image brightness are sampled and quantized. This 15 step generates an integer at each pixel representing the brightness or darkness of the image at that point.
A computer is a useful tool for solving a great variety of problems. To make a computer do anything (i.e. solve a problem), you have to write a computer program. In a computer program you tell a computer, step by step, exactly what you want it to do. The computer then executes the program, following each step mechanically, to accomplish the end goal.
Multimedia is the media that uses multiple forms of information content and information processing (e.g. text, audio, graphics, animation, video, interactivity) to inform or entertain the user. Multimedia also refers to the use of electronic media to store and experience multimedia content. Multimedia is similar to traditional mixed media in fine art, but with a broader scope. The term "rich media" is synonymous for interactive multimedia.
Growth : It is the increase in physical size of the whole body or any of the parts of the body. Because of cell division and synthesis of proteins. It causes a
quantitative change in the child's body. Growth can be measured accurately in inches, centimeters, pounds or kilograms.
“ ” is the process of organizing and planning how to divide
time between specific activities. Good time management enables to work smarter
– not harder – to get more done in less time, even when time is tight and
pressures are high. Failing to manage time damages the work effectiveness and
causes stress.
“ ” refers to the way that you organize and plan how long you
Data structure is a particular way of storing and organizing data in a
computer so that it can be used efficiently.
General data structure types include arrays, files, linked lists, stacks, queues,
trees, graphs and so on.
Data structures are classified into two types:
1- Linear data structures: elements can be accessed in a sequential order
(e.g. Arrays, Linked Lists, Stacks and Queues).
2- Non – linear data structures: elements can be accessed in a random order
(e.g. Trees, tables, sets, graphs).
