A Tracking‐By‐Detection Framework to Automatically Count Rare and Elusive Megafauna in Aerial Video Surveys

Remote Sensing in Ecology and Conservation, EarlyView.
Monitoring programs of vulnerable megafauna increasingly rely on aerial surveys from drones or planes fitted with cameras. However, automated methods are still lacking to accurately count individuals across entire surveys. Here, we leverage a tracking‐by‐detection framework to not only detect individuals but also link the resulting detections across ...

Robust steganographic framework for securing sensitive healthcare data of telemedicine using convolutional neural network

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract Data is the key element that runs the modern society. Large amounts of data are being released day by day as a result of many activities. The digital data is transferred through the Internet which may be vulnerable to attacks while transmitting. Especially, the medical data is observed to be of at most importance.

JPEG: the quadruple object [PDF]

, 2013
The thesis, together with its practice-research works, presents an object-oriented perspective on the JPEG standard. Using the object-oriented philosophy of Graham Harman as a theoretical and also practical starting point, the thesis looks to provide ...

Digital fragile watermarking scheme for authentication of JPEG images [PDF]

, 2004
It is a common practice in transform-domain fragile watermarking schemes for authentication purposes to watermark some selected transform coefficients so as to minimise embedding distortion.

DrLS: Distortion‐Resistant Lossless Steganography via Colour Depth Interpolation

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT The lossless data steganography is to hide a certain amount of information into a container image. Previous lossless steganography methods fail to strike a balance between capacity, imperceptibility, accuracy, and robustness, commonly vulnerable to distortion on container images.

Robust Multi‐Source Batch Normalisation for Test‐Time Batch Adaptation

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Test‐Time Batch Adaptation (TTBA) aims to adapt a pre‐trained source model to small, unlabelled target batches at test time. The TTBA methods focus on adapting the pre‐trained model or the target data in a one‐to‐one alignment paradigm. However, these one‐to‐one alignment paradigms assume that the source domain may share the same knowledge ...

The PhenoChange network protocol for monitoring leaf phenology in tropical dry ecosystems using phenocameras

Methods in Ecology and Evolution, EarlyView.
Abstract Tropical dry ecosystems (TDEs) cover half of the tropics and play a key role in global carbon dynamics. TDEs present distinct canopy and ground layers that often exhibit contrasting phenological patterns. On‐the‐ground observations of phenology by the human eye, though valuable, may suffer from limited temporal resolution and observer biases ...

Error resilience analysis of wireless image transmission using JPEG, JPEG 2000 and JPWL [PDF]

, 2009
The wireless extension of the JPEG 2000 standard formally known as JPWL is the newest international standard for still image compression. Different from all previous standards, this new standard was created specifically for wireless imaging applications.

JPEG with quadtree adaptive partitioning

Journal of Computer Science and Technology, 1999
In this paper two images compression techniques with loss based on the method used by the compression Standard Joint Photographic Experts Groups (JPEG) and on the Quadtree adaptive partitioning method are presented and compared, and the loss produced ...
