Sampling Exactly from the Normal Distribution
An algorithm for sampling exactly from the normal distribution is given. The algorithm reads some number of uniformly distributed random digits in a given base and generates an initial portion…

Unsupervised underwater fish detection fusing flow and objectiveness
In this paper, we propose a robust and unsupervised deep learning algorithm to automatically detect fish and thereby easing the burden of manual annotation.

FPGA acceleration for feature based processing applications
In this paper, we describe the implementation of an algorithm that combines distributed feature detector (D-HCD) with a rotational invariant feature descriptor (R-HOG).

Enabling Smart Camera Networks with Smartphone Processors
Distributed smart cameras exploit smartphone processor performance in their node communication and video metadata exchange, allowing the network to collectively reason in interpreting the scene, generating alerts, and making decisions.

Depth Extraction from Videos Using Geometric Context and Occlusion Boundaries
We propose to learn and infer depth in videos from appearance, motion, occlusion boundaries, and geometric context of the scene.

Re-Ranking by Multi-Feature Fusion with Diffusion for Image Retrieval
We present a re-ranking algorithm for image retrieval by fusing multi-feature information. We utilize pairwise similarity scores between images to exploit the underlying relationships among images.

Precise Vision-Aided Aerial Navigation
This paper proposes a novel vision-aided navigation approach that continuously estimates precise 3D absolute pose for aerial vehicles, using only inertial measurements and monocular camera observations.

Mining Structure Fragments for Smart Bundle Adjustment
In this work we show that, when using conjugate gradient solvers, there is a computational advantage in “grouping” factors corresponding to sets of points (fragments) that are co-visible by the…
