Lip Reading Based Surveillance System

In this paper we propose a lip reading recognition technique designed to be a part of a surveillance system and will be used for physical security. The proposed technique would be used for security issues using motion estimation analysis, applying a new five step search block matching algorithm.. The proposed technique is characterized by high speed performance suitable for real time applications. The three-step search (TSS) algorithm has been widely used as the motion estimation technique in some low bit-rate video compression applications, owing to its simplicity and effectiveness. However, TSS uses a uniformly allocated checking point pattern in its first step, which becomes inefficient for the estimation of small motions. The lip recognition technique deemed valuable in fast recognition of lip reading that can be used in security paradigm for real time applications like password entries that are shoulder surfing resilient.
