|
|
|
| n | Consider
the block of 4 pixels a,b,c,d |
|||
| n | These
can be considered a 4d vector |
|||
| n | [a,b,c,d]
expressed in the basis Space |
|||
| a |
| b |
| c |
| d |
|
|
|
|
|
| Or in
numbers [1,0,0,0], [0,1,0,0], [0,0,1,0], [0,0,0,1] |
||||
| The
pixel values are the results of performing inner |
||||
| product
operations between the patch and the pixel |
||||
| basis
vectors which select out individual |
||||
| ‘dimensions’ of
the patch. |
