SIGNAL AND IMAGE PROCESSING (SIP) GROUP


Group Leader: Dr Bhanu Prakash KN

Research Overview

Signal and Image processing (SIP) Group’s main focus is on the development of signal and image processing systems and algorithms. Combining machine learning techniques, biological vision models and signal statistics, the group develops advanced image analysis tools for SBIC. The SIP actively participates in ongoing and future projects of SBIC and actively collaborates with all the groups. SIP also focuses on development of novel algorithms for post-processing to extract meaningful information which enables detection, characterization and quantization of clinically significant information. SIP aims to develop new skills and knowledge in advanced multi-modal image acquisition (MR, CT, PET, Optical), signal, and image processing, contribute to IP and publish in prestigious journals.  

SIP is currently focused on using machine learning and deep learning for MR data processing applications such as Image super-resolution, Image reconstruction from partial k-space acquisition and generation of quantitative maps. This work is aimed at reducing imaging related costs, patient discomfort, enabling new diagnostic biomarkers and increasing the imaging throughput efficiency. Apart from the above, we are also working on automatic brain extraction and segmentation of marmoset images, Identification of ROIs involved in remembering and recollection process from fMRI images, Stroke lesion segmentation from unenhanced CT and segmentation of ventricular system and brain structures for NPH.

Mission Statement

The Signal and Image Processing (SIP) group is a supporting group whose purpose is to create, develop and implement state-of-the-art signal and image processing resources to SBIC; educate the SBIC’s scientific groups in signal and image processing; and provide a platform for researchers of SBIC to interact and exchange ideas in post-processing. 

Vision Statement

The Signal and Image Processing (SIP) group aims to be the distinguished information and resources group in signal and image processing to SBIC. We achieve this by providing a variety of state-of-the art algorithms to SBIC research problems that are customized to each group; adapting/updating to a rapidly changing technical know-how; and being closely involved in the post-processing activities of each group at all levels.
