Abstract

Scientific discovery is continuously enabling the development of marvelous new devices based on new technology being offered to the public. In fact, new or improved devices are hitting the market so fast we sometimes feel drowned by them. It is hard to keep up with the many wonderful new possibilities available in photography, making, choosing and playing music, communicating, producing and reproducing things etc.



Our ability to benefit from this new technology is possible only when we can use it. This is not always easy.



I think that engineers who make the development of these wonderful devices or develop them do not always think of final operability for the uninitiated in their design of new products. The new services and devices created by new technology often require a great deal of expertise to use because the engineers who create them do so with their own technological understanding in mind.



I believe that it should be our task as engineers to develop devices and services which can be easily used by everybody.



One way to achieve this is by including intelligence in our creations. It would be wonderful if every device could check its own health and communicate its state to the person using it. It would be great if every device, when it detected a person doing something with it, could guide that person in its use.

Abstract

Advances on CIS technologies, heterogeneous packaging and system embedding enable to reduce Size, Weight and Power (SWaP) of vision systems. Vision can hence be incorporated to applications calling for minimum SWaP, such as vision-enabled wireless sensor networks, unattended surveillance networks, low payload vehicles, personal portable vision equipment, visual prosthesis, internet-of-the-things, etc. These applications are forecast to gain relevance in the coming years as compared to the dominant CIS niche of smart phones, tablets and other consumer domains.



These new applications domains have technical challenges different from those of consumer ones. Thus, while consumer applications call for images that can be reproduced with all their fine details for their interpretation by humans, many of these new applications call for extracting the information contained into the images for their interpretation by machines. Subtle details of the images are irrelevant in many cases and may hence be discarded for storage and processing. In summary, the domain of electronic imaging and CIS technologies is witnessing a move from “displaying”, for interpretation by humans, to “analysing”, for interpretation by computers.



Confronting the scientific challenges of such a move requires using computer vision concepts for the design of new generations of smart image sensor front-ends. The endeavour is challenging because imager architects and computer vision architects have traditionally non-overlapping groups talking quite different languages. However, synergies among these two disciplines are needed to conceive new sensor front-ends that are capable to achieve minimum power and maximum efficiency by discarding irrelevant data right at the sensory front-end and precluding them to propagate into the system calling for storage and processing resources.



Data reduction through pre-processing is smartly implemented in natural vision systems [1], [2]. Also, this approach has been extensively addressed in academia during the last years and vision systems using such architectural concept are recently making the transition from academic proof-of-concept prototypes to industrial products [3].



Starting with the identification of relevant computer vision primitives for data reduction across the vision processing chain, this presentation discusses different smart-image sensor architectures for feature extraction. Besides explaining basic architectural concepts and circuits needed to implement them, the presentation shows results from several proof-of-concept chips, from camera modules built with these sensors and from portable vision application demos using these camera modules.

Abstract

Gene Regulatory Network (GRN), which is made up of interacting regulators such as DNA, RNA, proteins and their complexes, controls the expression levels of mRNA and proteins. GRNs govern several cellular processes such as metabolism, signalling, cell-differentiation, cell-division, cell-cycle arrest in response to DNA damage, and apoptosis. Understanding the dynamics of GRNs by introducing accurate models and then applying efficient mathematical/computational methods for their analysis is useful in identifying the underlying mechanisms of normal and abnormal cell functioning and hence developing drugs against diseases including cancer. Bistability and oscillations are two crucial nonlinear dynamical behaviours observed in a diverse area of biological systems, in particular, gene regulatory networks. As in many others including electrical systems, bistability and oscillation phenomena appear as consequences of specific patterns of interactions such as positive/negative feedback loops among the components of GRN and they have a certain function on the control of gene expression to regulate the cellular processes and adaptation to the changing environment. The bistability in GRN is a biological switching mechanism accompanied with hysteresis. It appears in a wide variety of GRNs including the lac operon of Escherichia coli, which is responsible for controlling the lactose metabolism under glucose starvation. The bistable genetic switches with their hysteresis characteristics behave, like a thermostat, as ON/OFF controllers avoiding unnecessary transitions between induced and uninduced states of the associated operon. On the other hand, the oscillations in GRN, such as circadian rhythm and 2-phase dynamics of tumour suppressor p53 network, are of essentially relaxation type providing constant amplitude and period, and possess self-sustaining property and the ability of synchronization to the environmental inputs and to the interlinked networks. The behaviour of GRNs is generally modelled by using the state equations with rational right hand sides derived from enzyme kinetics based on Michaelis-Menten and/or Hill approaches. The talk will present a series of studies on bifurcation and local stability analysis of some primary examples of bistable switches and relaxation oscillators appearing in GRNs.
