Patent ID: 6928228

Claim:
A method for detection and analysis of video recording, the method comprising: receiving a video recording; calculating complexity values of video recording received, wherein the calculating of complexity values comprises the following steps, partitioning said video recording into sub-unit blocks of a pre-determined size; creating at least one complexity catalog based on said video recording, the complexity catalog containing complexity values of the sub-unit blocks; and characterized in that the step of creating the at least one complexity catalog comprises: creating a list of word sizes concerning the content of the sub-unit blocks in accordance with the format of said video recording; determining a range of values constituting the sub-unit block in accordance with the format of said video recording; computing a usage value for each word size in the list of word sizes, the usage value being the ratio between the number of different words present in the sub-unit block to the maximum number of possible words; and computing the complexity value of the sub-unit block, the complexity value being the product of the usage values obtained in the previous step; comparing the calculated complexity values with reference complexity values; and displaying analysis of video recording on a user interface.
