Resumen:
Multimedia data grows fast due to advances in information technologies,
creating the demand for efficient video indexing and object retrieval
techniques. Traditional methods consume significant computational
resources such as storage space and processing time. In this paper we
propose an efficient content-based video retrieval system that is based
on three main stages. The first stage involves computing the DC-image of
each I-frame, from which a summarization process to extract key-frames
is performed. During the second stage, a segmentation processes is
applied to each key-frame in order to isolate the region of interest
within it. Local features are extracted from the resulting area and are
stored as the descriptor of the frame. The retrieval stage is carried
out by computing the Euclidean distance and determines if its content is
related with the video database. Experimental results show that the
proposed approach is promising in terms of efficiency and effectiveness.
