  • Sparse Modeling

    Sparse Modeling in Image Processing and Deep LearningSparse approximation is a well-established theory, with a profound impact on the fields of signal and image processing.

  • Immersive Optical-See-Through Augmented Reality (Keynote Talk)

    Immersive Optical-See-Through Augmented Reality. Augmented Reality has been getting ready for the last 20 years, and is finally becoming real, powered by progress in enabling technologies such as graphics, vision,...

  • Performance Benchmarks for Detection Problems

    We propose a benchmark curve that measures the inherent complexity of a detection problem. The benchmark curve is built using a sequence of simple detection methods based upon random projection.

  • Numerical differentiation of noisy, nonsmooth, multidimensional data

    We consider the problem of differentiating a multivariable function specified by noisy data.

  • Counting Plants Using Deep Learning

    In this paper we address the task of counting crop plants in a field using CNNs. The number of plants in an Unmanned Aerial Vehicle (UAV) image of the field is estimated using regression instead of classification.

  • Fitness Heart Rate Measurement Using Face Videos

    Recent studies showed that subtle changes in human’s face color due to the heartbeat can be captured by digital video recorders. Most work focused on still/rest cases or those with relatively small motions.
