Study Notes
Image Representation
- A greyscale image is represented in a color format of varying shades of grey, ranging from pure black to pure white.
Binary Image Storage
- A binary image of size 512 x 512 requires 262,144 bytes of storage.
True Color (RGB) Image
- A true color (RGB) image has a total of 3 indices, one for each primary color: Red, Green, and Blue.
Image Resolution
- The resolution of a greyscale image is not specified, but it can be measured in terms of the number of pixels per unit length.
Pixel Value
- In a given picture element (pixel), the value 0 represents pure black.
Image Processing
- Object detection involves finding lines, circles, or particular shapes in an image.
Image Restoration
- Image restoration involves the process of removing degradations and reconstructing the original image from a corrupted or distorted one.
Image Processing Module
- The third step in the module 'Introduction to Image Processing' is not specified.
Matlab Functions
- The 'imshow' function in Matlab is used to display an image.
- The 'impixelinfo' function in Matlab is used to display information about the pixel at the location clicked.
- The 'figure' function in Matlab is used to create a new figure window.
- The 'uint8' type in Matlab is used to represent an 8-bit unsigned integer, typically used for image data.
- The 'imresize' function in Matlab is used to resize an image.
- The 'imread' function in Matlab is used to read an image file.
