Using hidden Markov models to deal with availability bias on line transect surveys

, 2013
This work was supported by EPSRC grant EP/I000917/1We develop estimators for line transect surveys of animals that are stochastically unavailable for detection while within detection range.

Wrinkle Detection Using Hessian Line Tracking

IEEE Access, 2015
Wrinkles play an important role in the face-based analysis. They have been widely used in applications, such as facial retouching, facial expression recognition, and face age estimation. Although a few techniques for a wrinkle analysis have been explored

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Assessing the impact of signal normalization: Preliminary results on epileptic seizure detection [PDF]

, 2011
21.08.12 KB. Accepted version, ok to add to Spiral. IEEE policy.Signal normalization is an essential part of patient independent algorithms, for example to correct for variations in signal amplitude from different parts of the body, prior to applying a ...

A variant of the Hough Transform for the combined detection of corners, segments, and polylines

EURASIP Journal on Image and Video Processing, 2017
The Hough Transform (HT) is an effective and popular technique for detecting image features such as lines and curves. From its standard form, numerous variants have emerged with the objective, in many cases, of extending the kind of image features that ...

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Evolving a Dynamic Predictive Coding Mechanism for Novelty Detection [PDF]

, 2007
Novelty detection is a machine learning technique which identifies new or unknown information in data sets. We present three evolutionary algorithms, a simple genetic algorithm, NEAT and FS-NEAT, for the the task of optimising the structure of an ...

HODet: A New Detector for Arbitrary-Oriented Rectangular Object in Optical Remote Sensing Imagery

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Object detection from remote sensing images is a key technology for Earth observation applications, which has important scientific research value. Ground objects in remote sensing images appear at arbitrary angles.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Moment-preserving line detection

, 2009
[[abstract]]A new method for line detection in two-dimensional image data is presented. Based on the moment-preserving principle, the method is developed to estimate line location and width to the subpixel accuracy within a circular mask.
