Method and system of identifying one or more features represented in a plurality of sensor acquired data sets
First Claim
1. A method of identifying one or more features represented in a plurality of sensor acquired data sets, the method comprising:
- determining a first probability of the identity of the one or more features from a first one of the data sets;
determining a second probability of the identity of the one or more features from a second one of the data sets;
fusing the determined first and second probabilities to provide a fused probability; and
identifying the one or more features from the fused probability.

Abstract
A method and system for identifying one or more features represented in a plurality of sensor acquired data sets is described. The method and apparatus is particularly useful in automatic license plate recognition applications, where the sensor acquired data sets are data obtained from one or more digital cameras. This is achieved by determining a first probability of the identity of the one or more features (e.g., alphanumeric characters) from a first one of the data sets; determining a second probability of the identity of the one or more features from a second one of the data sets; and, using data fusion techniques, fusing the determined first and second probabilities to provide a fused probability. This fused probability is used to identify the one or more features from data sets.

16. A method of identifying a vehicle registration number from a plurality of images comprising representations of a vehicle registration plate, the method comprising:
-
determining a first probability distribution of alphanumeric characters present in a portion of one of the images; determining a second probability distribution of alphanumeric characters present in a portion of another of the images, the portion of the other of the images corresponding to the portion of the one of the images; fusing the first and second probability distributions to provide a fused probability distribution of alphanumeric characters in relation to the one and the other images; and identifying which alphanumeric character is present in the respective portions of the one and the other images by identifying from the fused probability distribution the alphanumeric character having the highest probability of being present. - View Dependent Claims (17, 18)
