Concise summary of key research projects:
Research
Study on novel techniques to improve efficiency of signal detection in next-generation communication systems.
Location: LSSI Lab, UQTR, QC, Canada
- With the surge in next-generation communication system applications, there is an increasing demand for advanced capabilities of computing circuits catering them.
- The overall work addresses the challenge of developing integrated techniques for next-generation communication systems to achieve controlled trade-off between following KPIs :
- Energy consumption
- Computational complexity
- Interconnect Bandwidth
- Throughput
- Latency
- Signal Fidelity
- Algorithm decentralization and approximate computing approaches are utilized in the work for SISO/MIMO signal detection.
- Evaluation of techniques on FPGA computing platform.
Improving Accuracy of Superpixel Segmentation using Color Histogram-based Seed Initialization
Location: HESL Lab, NTU SCSE, Singapore
- Superpixels are perceptually meaningful image segments formed by grouping pixels based on common properties, such as color, and are useful for accelerating computer vision applications.
- In this work, the Histogram Super Linear Iterative Clustering (SLIC) algorithm is prototyped to enhance the accuracy of the SLIC algorithm by using a color histogram during seed initialization. The quantized color histogram captures localized color profiles within uniform grids in the raw image.
- The quality of initial seeding can be controlled through user-defined parameters, such as histogram suppression window and maximum seeds per grid box.
- Label enforcement of erroneous pixels is implemented on the superpixel segmented image by assigning a pixel with a particular cluster label based on the majority of surrounding labels.
