We present a new method to extract scale-invariant features from an image by using a Cosine Modulated Gaussian (CM-Gaussian) filter. Its balanced scale-space atom with minimal spread in scale and space leads to an outstanding scale-invariant feature detection quality, albeit at reduced planar rotational invariance. Both sharp and distributed features like(More)
Exploitation of spatial locality is essential for memories to increase the access bandwidth and to reduce the access-related latency and energy per word. Spatial locality exploitation of a kernel can be improved by modifying placement of data in memory, but this may be felt not only by the kernel itself, but also in other application components accessing(More)
A recently designed hyperspectral imaging device enables multiplexed acquisition of an entire data volume in a single snapshot thanks to monolithically-integrated spectral filters. Such an agile imaging technique comes at the cost of a reduced spatial resolution and the need for a demosaicing procedure on its interleaved data. In this work, we address both(More)
Future dynamic applications will require new mapping strategies to deliver power-efficient performance. Fully static design-time mappings will not be able to optimally address the unpredictably varying application characteristics and system resource requirements. Instead, the platforms will not only need to be programmable in terms of instruction set(More)
The second edition of the " international-Traveling Workshop on Interactions between Sparse models and Technology " (iTWIST) took place in the medieval and picturesque town of Namur in Belgium. The workshop was conveniently located in " The Arsenal " building within walking distance of both hotels and town center. One implicit objective of this biennial(More)

To enable industrial adoption of hyperspectral imaging we have developed a unique integrated hyperspectral filter/imager technology. The spectral filters are monolithically deposited/integrated on top of CMOS imagers at wafer level. The materials of the filters are chosen such that they are compatible with the production flows available in most CMOS(More)
