Data Structure 2

Given a query image:

• The image is truncated and quantized giving a 2-D array Q with (-1,0,1) as entries

• A scoring array indexing all database elements is generated.

• For each indexing pair (i,j) with Q[i,j]ɬ, the elements in D+ are used to update the scoring array (same for Q[i,j]ɘ)
