PHD POSITIONS ON "Image/Video Enhancement for Embedded Devices"
Two PhD positions/studentships to study advanced algorithms for image/video
enhancement for embedded devices (e.g., single-sensor imaging) are available as
special track of the 3-year PhD program (Dottorato in Informatica) at the
University of Catania (Italy) c/o the Image Processing Lab
The studentships are sponsored by STMicroelectronics - AST (Advanced System
Technology) Imaging Catania Lab
The research program aims at the development of new algorithms and methods for
the processing of digital images acquired by single-sensor imaging devices.
Cameras make use of an electronic sensor (Charge Coupled Device/Complementary
Metal-Oxide-Semiconductor) to acquire the spatial variations in light intensity
and then use image processing algorithms to reconstruct a color picture from
the data provided by the sensor. Acquisition of color images requires the
presence of different sensors for different color channels.
Manufacturers reduce the cost and complexity by placing a color filter array
(CFA) on top of a single image sensor, which is basically a monochromatic
device, to acquire color information of the true visual scene. Typical imaging
pipelines implemented in single-sensor cameras are usually designed to find a
trade-off between sub-optimal solutions (devoted to solve imaging acquisition)
and technological problems (e.g., color balancing, thermal noise, etc.) in a
context of limited hardware resources.
In this project, novel algorithms will be designed by making use of
innovative solutions able to outperform traditional image generation pipelines.
In particular, we plan to investigate about algorithms and methods occurring at
all stages of the whole pipeline. More specifically, we claim that there is
space for optimization and innovation related to specific processing into CFA
domain (demosaicing, zooming, enhancement, denoising, compression,
stabilization). In addition one of the main objectives of the project is the
integration of the classic pipeline with innovative methods for scene
recognition and understianding. Ultimate goal of the project is the realization
of a new concept of digital camera, able to output an image more closely
resembling the scene perceived by the user investigating about techniques of
the whole classic imaging pipeline.
