  • Research TopicSensor noise & Low-level vision
Project : The Development of Sensor Noise Model based Low-level Image Processing
Purpose ● Development of noise model and low-level image pre-processing methods
● Development of ISP by HW dedicated IP and low-power and area optimization
● Depth accuracy enhancement by semantically meaningful edge extraction robust to lens blur and illumination changes
Contents ● Image noise and distortion correction for enhancing depth accuracy
- Development of noise removal method by modeling sensor noise itself in low-light condition
- Development of blur removal method based on correct motion estimation by calibrating vision and IMU

● Low-power Sensor Noise Model-based Denoising & distortion removal Hardware IP
- Low-power and area optimization of noise removal algorithm for implementing ASIC
- Development of a dedicated hardware IP to satisfy the performance with low-power simultaneously

● Edge detection robust to image blur and illumination changes for enhancing depth accuracy
- Development of depth extraction method using RGB and IR image pair
- Development of robust edge detection method using RGB and depth
Expected Contribution
● Market activation of security systems and smart devices with ISP having strong noise and distortion removal ability in low-light condition
● Creation of new market due to improved recognition performance using enhanced input for various applications such as mobile robots, smart cars and smart devices
