Patent ID: 8879855

Claim:
A method for fine-grained image classification on an image, comprising: automatically segmenting one or more objects of interest prior to classification; combining segmented and original image features before performing final classification; determining an affinity matrix W, using a feature representations f i of each pixel: W ij = exp ( -  f i - f j  2 2 ⁢ σ 2 ) ; minimizing a cost function C(X) with respect to all pixel labels X: C ⁡ ( X ) = 1 2 ⁢ ∑ i , j - 1 N ⁢ ⁢ W ij ⁢  X i D ii - X j D jj  2 + ∑ i - 1 N ⁢ ⁢ λ 2 ⁢  X i - Y i  2 where D ii =Σ j=1 N W ij , and Y i are the desired labels for pixels; and solving an optimal solution for X as a system of linear equations: ((1+λ) I−S ) X=λY X= λ((1+λ) I−S ) −1 Y.
