Study Notes
Digital Image Representation
- A digital image I(r, c) is represented as a 2D array of intensity values, where r and c denote the row and column indices respectively.
Gray Scale Image
- A typical gray scale image can contain 256 different brightness levels, or 2^8 levels.
Binary Image
- A binary image is a digital image that can have only two intensity values, typically represented by 0 (black) and 255 (white).
Color Image Modeling
- A color image can be modeled as a combination of three 2D arrays, one for each primary color (red, green, and blue).
Monochrome Image Data
- The digital image data of a monochrome image stores intensity values, representing the brightness of each pixel.
Linear Algebra Representation
- A two-dimensional array like a digital image is referred to as a matrix in linear algebra terms.
Image File Formats
- TIFF (Tagged Image File Format) is recommended for high-quality prints, professional publications, and archival copies.
- BMP (Bitmap) files use uncompressed raster image format, which results in large file sizes.
- GIF (Graphics Interchange Format) is best suited for web graphics due to its ability to be animated and to save transparency.
- JPEG (Joint Photographic Experts Group) is a compressed image format that reduces the file size by selectively discarding some of the data.
GIF File Limitations
- GIF files are limited to 8-bit color, which means they can display up to 256 different colors.
JPEG File Suitability
- JPEG files are suitable for web use and non-professional prints.
Windows Image File Format
- WDP (Windows Media Photo) is an image file format developed by Microsoft for Windows.
TIFF Characteristics
- TIFF is known for allowing very high-quality images, but also resulting in larger file sizes.
