Abstract:
Ever since image sensors replaced films, we witnessed a major advancement
of image processing research that enabled a fast, high quality image
acquisition. Our consumption of digital images have been reshaped by
the ubiquity and availability of digital cameras, and emergence of new
systems built "on top" of cameras (e.g. multimedia, video conferencing,
3D cameras, surveillance, swallowable camera, social networking) make much
out of available camera technology. Despite the considerable progress,
challenges stemming from system integration, pixel miniaturization,
speed, complexity, and power have continued to evolve over time as well.
The goal of this talk is to understand the limitations of modern
digital camera processing pipeline architecture and outline future
directions aimed at overcoming them. Based on often overlooked aspects
of sampling, noise, and color fidelity problems, I will propose a model
that explains the underlying interactions between various stages of
image acquisition processing pipeline and admits computational and
image quality optimization over the whole acquisition system. This
representation provides the means to design a new versatile, high quality,
and high performance digital camera that meets the demands of low light,
high resolution, and low complexity requirements.
