Non-local Image Dehazing
TLDR
This work proposes an algorithm, linear in the size of the image, deterministic and requires no training, that performs well on a wide variety of images and is competitive with other state-of-the-art methods on the single image dehazing problem. Expand
Seam carving for content-aware image resizing
TLDR
This work presents a simple image operator called seam carving that supports content-aware image resizing for both reduction and expansion, and support various visual saliency measures for defining the energy of an image, and can also include user input to guide the process. Expand
Fast Human Detection Using a Cascade of Histograms of Oriented Gradients
TLDR
This work integrates the cascade-of-rejectors approach with the Histograms of Oriented Gradients features to achieve a fast and accurate human detection system that can process 5 to 30 frames per second depending on the density in which the image is scanned, while maintaining an accuracy level similar to existing methods.

Seam carving for content-aware image resizing
Effective resizing of images should not only use geometric constraints, but consider the image content as well. We present a simple image operator called seam carving that supports content-awareExpand

TLDR
This work considers tracking as a binary classification problem, where an ensemble of weak classifiers is trained online to distinguish between the object and the background, and combines them into a strong classifier using AdaBoost. Expand
Improved seam carving for video retargeting
TLDR
This work replaces the dynamic programming method of seam carving with graph cuts that are suitable for 3D volumes and presents a novel energy criterion that improves the visual quality of the retargeted images and videos. Expand
Locally Orderless Tracking
TLDR
This work provides a probabilistic model of the target variations over time and rigorously shows that this model is a special case of the Earth Mover’s Distance optimization problem where the ground distance is governed by some underlying noise model. Expand
Multi-operator media retargeting
TLDR
A new image similarity measure is defined, which is term Bi-Directional Warping (BDW), and used with a dynamic programming algorithm to find an optimal path in the resizing space and shows how a path in this space defines a sequence of operations to retarget media. Expand

TLDR
This work shows results of using a homogeneous quadratic polynomial kernel-SVT for vehicle tracking in image sequences and builds pyramids from the support vectors and uses a coarse-to-fine approach in the classification stage. Expand
