Journal ArticleDOI
Object Trajectory-Based Activity Classification and Recognition Using Hidden Markov Models
TL;DR: This paper presents novel classification algorithms for recognizing object activity using object motion trajectory, and uses hidden Markov models (HMMs) with a data-driven design in terms of number of states and topology.
Journal ArticleDOI
Quantitative Immunohistochemistry by Measuring Cumulative Signal Strength Using Commercially Available Software Photoshop and Matlab
TL;DR: A novel algorithm is described based on calculating the cumulative signal strength, or energy, of the digital file representing any portion of an image that can determine the absolute amount of antibody-specific chromogen per pixel for any cellular region or structure.
Journal ArticleDOI
Robust Video Stabilization Based on Particle Filter Tracking of Projected Camera Motion
TL;DR: A novel technique for video stabilization based on the particle filtering framework that extends the traditional use of particle filters in object tracking to tracking of the projected affine model of the camera motions and relies on the inverse of the resulting image transform to obtain a stable video sequence.
Journal ArticleDOI
Optimal morphological pattern restoration from noisy binary images
Dan Schonfeld,John Goutsias +1 more
TL;DR: It is proved that the class of alternating sequential filters is a set of parametric, smoothing morphological filters that best preserve the crucial structure of input images in the least-mean-difference sense.
Journal ArticleDOI
Real-Time Motion Trajectory-Based Indexing and Retrieval of Video Sequences
TL;DR: This approach solves the problem of trajectory representation when only partial trajectory information is available due to occlusion, by a hypothesis testing-based method applied to curvature data computed from trajectories.
