Image based face detection and verification is a well researched topic and has found many applications. The limitation with image based techniques is that 3D real world objects are mapped on to a 2D plane, which causes loss of 3D features of real objects. Multiple systems are available in literature to estimate depths of objects viz. stereo images, 3D and 2.5D scanners, etc. However, these systems...
With the advancement in technology and the inherent advantage of voice based communication due to its variability, speed and conveneince has driven attention towards mechanical recognition of speech. Literature survey of research in this area shows that almost every system uses Gaussian Mixture Hidden Markov model for optimal performance in recognition of speech. Evaluation of Gaussian likelihood...
