Exact algorithm for segment based sequence alignment
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)In bioinformatics, proteins, large biological molecules consisting long chain of amino acids, are described by a sequence of 20 amino acids. To analyze these protein sequences pairwise alignment is being used, which ... -
Exploring suitable classifier for robust face and facial expression recognition.
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)Face recognition by machines has been studied since last few decades and the problem is attempted to be solved by various ways. However any robust solution is not acheived yet by the researchers due to numerous challenges ... -
Eye localization in video: a hybrid approach
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)Location of eyes is an important process for operations such as orientation correction, which are necessary pre-processes for face recognition. As eyes are one of the main features of the human face, the success of facial ... -
Fingerprint image preprocessing for robust recognition
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)Fingerprint is the oldest and most widely used form of biometric identification. Since they are mainly used in forensic science, accuracy in the fingerprint identification is highly important. This accuracy is dependent ... -
High-speed 512-point FFT single-chip processor architecture
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)This thesis present a fully parallel novel fixed point 16-bit word width 512 point FFT processor architecture. The 512 point FFT is realized by decomposing it into three 8 point FFT units. This approach reduces the number ... -
Human action recognition in video
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)Action recognition is a central problem in computer vision which is also known as action recognition or object detection. Action is any meaningful movement of the human and it is used to convey information or to interact ... -
Image ranking based on clustering
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)In a typical content-based image retrieval (CBIR) system, query results are a set of images sorted by feature similarities with respect to the query. However, images with high feature similarities to the query may be very ... -
Learning to rank: using Bayesian networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)Ranking is one of the key components of an Information Retrieval system. Recently supervised learning is involved for learning the ranking function and is called 'Learning to Rank' collectively. In this study we present ... -
