Patent ID: 8879622

Claim:
A method for on-line transmission of a high-resolution video sequence comprising T images, where T is the total number of images of the high-resolution video sequence, the method comprising, for each image I(t) of said video sequence, determining whether to select said image I(t) for transmission by: splitting each image I(t) to be transmitted at an instant t into N zones, where N is the total number of image zones in each image I(t); calculating, for each zone n of the N zones, a value ν n (t) representative of content of said zone; generating, for each image I(t) to be transmitted, a vector V n (t) of size N representative of content of said image and containing the values ν n (t) for each of the N zones, wherein V N (t)=[ν 0 (t), . . . , ν N-1 (t)] T , [·] T is a transposition operator for a vector; calculating a normalized coefficient of correlation α between a reference vector R N (k)=V N (t 1 )=[r 0 (k), . . . , r N-1 (k)] T determined for an image previously selected for transmission at a previous instant t 1 I sel (k−1)=I(t 1 ) and the vector V N (t) calculated for the image I(t) according to α = R N T ⁡ ( k - 1 ) · V N ⁡ ( t ) R N T ⁡ ( k - 1 ) · R N ⁡ ( k - 1 ) · V N T ⁡ ( t ) · V N ⁡ ( t ) , where k is a temporal index of a selected image; determining whether to transmit the image I(t) by comparing the value of the normalized coefficient of correlation α with one or more thresholds having predetermined values; and replacing, if the image I(t) is transmitted, said image previously selected for transmission at a previous instant t 1 I sel (k−1)=I(t 1 ) by said image I(t).
