Identifying camcorders using noise patterns from video clips recorded with image stabilisation

Comparing the noise pattern from two digital video clips is a way to investigate if the same camcorder has been used to shoot both clips. Many camcorders have functions to compensate for shaky movements, and some of these functions affect the possibility to extract the noise pattern. This paper presents a method to compensate for the stabilisation when extracting the noise pattern. Eight clips with different characteristics were recorded by the same camcorder. When the noise patterns extracted from these clips were compared to three clips from different camcorders, a better result was achieved with the proposed method.
