| Example:
Color Histogram |
|
|
|
|
|
|
|
|
|
|
| | Each
pixel has color depth (e.g., 16 bits) |
||||||||
| | Divide
image into regions (e.g., 8x8 pixels) |
||||||||
| | Create
a histogram for each region (amount |
||||||||
| of
red, cyan, etc.) |
|||||||||
| | The
set of histograms serves as a |
||||||||
| quantitative
representation for the image, |
|||||||||
| allowing
comparisons and rankings |
|||||||||
| | Querying
awkward (use QBE) |
