“…The most common patterned textures for investigation were lace [16,17,42,43] and Jacquard fabrics [20,44,[129][130][131][132][133][134]. The methods used could be broadly classified as template-matching approach, and statistical & spectral approach, which are termed hybrid approach.…”

“…Hash function method, utilizing the offset properties between defect-free and template patterned textures, was a 1D approach and sensitive to small changes in pattern. Four types of Hash function detected defects from simple to complex textures in [130,135]. Previously, an image block densitometrical profile [136], equivalent to the checksum Hash function in [130,135], was proposed.…”

Abstract-With the continuous recording of video data in current surveillance systems, it is almost impossible to quickly identify frames where events of interest did occur within a camera scene. This paper presents the concept of Spatio-temporal Indexing, which is a novel video indexing and retrieval technique that can be used for event detection. Spatio-temporal Indexing allows the users to rapidly retrieve the video clips that contain events of interest from a given video library. The proposed indexing technique analyzes the video and stores the Spatio-temporal Indexes that will be further processed to retrieve video clips queried by users. The proposed technique was tested on hours of video recordings. The results obtained provide 99.9% accuracy for event detection and retrieval. The average processing time is 3 seconds to create index for 10 minutes of videousing Intel i5-2400 processor.Index Terms-Incident investigation, video indexing, video summarization, video retrieval.
