Issue: non-temporal real-time fire detection via reduced complexity deep CNN architectures.
Approach: experimentally define reduced complexity deep convolutional neural network (CNN) architectures based on leading references architectures
Application: suited to embedded detection devices for edge computation.
Considers real-time performance for two discrete fire detection tasks:- full-frame fire detection and in-frame localization via super-pixels
Performance achieved upto 95% detection accuracy for full-frame fire detection and 97% accuracy for in-frame superpixel localisation with processing at 40 fps (full-frame) or 18 fps (localisation).3 results

Issue: Real-time derivation of highly detailed visual saliency maps.
Approach:Division of Gaussians (DIVoG) comprising three distinct steps: (1) Bottom-up Gaussian pyramid construction, (2) Top-down Gaussian pyramid construction using (step 1), (3) Element-wise division of input image with (step 2).
Application: Real-time performance of DIVoG is 6x faster for 3-channel images and 16x faster for single channel images.
In contrast to other approaches DIVoG is not dependent on colour information (steps 1-3).
Overall this approach (DIVoG) produces high detail real-time saliency maps at a fraction of the computational cost of other methodologies in earlier work. A wide range of real-time applications can benefit from this approach including object detection and classification.2 results

Issue: Prior real-time fire detection work relies upon a combination of basic colour spectroscopy and temporal information with no explicit use of texture features.
Approach: 1) Candidate fire region extraction via colour spectroscopy; followed by 2) per-region classification using colour-texture feature vector extraction targeted from earlier candidate region isolation.
Application:The approach is shown to operate successfully over a range of environmental and combustion conditions. Maximal performance of 98% detection is achieved at 12fps on (small) 360x288 resolution imagery.
The use of colour-texture features as an input to a trained classifier outperforms simple spectroscopy and is independent of temporal feature information. Two stage spectroscopy based region isolation and colour-texture feature classification limits required texture statistic computation facilitating their use within real-time bounds.1 result

Issue: The automatic detection and classification of biological cells within histological tissue sample imagery is an important step in the development of automated microscopy procedures for the support of medical diagnosis and research. This task is primarily related to high-throughput cell screening and analysis microscopy applications.b
Approach: our work has concentrated upon the cell detection problem in isolation where we employ a novel combination of Laplace-edge features and a Support Vector Machine (SVM) classifier to determine accurate and reliable cell detection.
Application: This feature-driven approach (trained on data at a single scale, single stain type) illustrates remarkable generalisation over a range of microscopy image scales and stain types (see above). The SVM is trained using cross-validation based grid search within the SVM parameter space with optimal results (~92% correct detection) achieved using an RBF type SVM kernel.1 result
