detection of candidatus liberibacter asiaticus in diaphorina citri and its importance in the management of citrus huanglongbing in florida
Phytopathology, 2008Co-Authors: K L Manjunath, Susan E Halbert, Chandrika Ramadugu, Susan E WebbAbstract:Manjunath, K. L., Halbert, S. E., Ramadugu, C., Webb, S., and Lee, R. F. 2008. Detection of ‘Candidatus Liberibacter asiaticus’ in Diaphorina citri and its importance in the management of citrus huanglongbing in Florida. Phytopathology 98:387-396. Citrus huanglongbing (HLB or citrus greening), is a highly destructive disease that has been spreading in both Florida and Brazil. Its psyllid vector, Diaphorina citri Kuwayama, has spread to Texas and Mexico, thus threatening the future of citrus production elsewhere in mainland North America. Even though sensitive diagnostic methods have been developed for detection of the causal organisms, Candidatus Liberibacter spp., the pathogen cannot be detected consistently in plants until symptoms develop, presumably because of low titer and uneven distribution of the causal bacteria in nonsymptomatic tissues. In the present study, TaqMan based real-time quantitative polymerase chain reaction methodology was developed for detection of ‘Ca. L. asiaticus’ in D. citri. Over 1,200 samples of psyllid adults and nymphs, collected from various locations in Florida, from visually healthy and HLB symptomatic trees at different times of the year were analyzed to monitor the incidence and spread of HLB. The results showed that spread of ‘Ca. L. asiaticus’ in an area may be detected one to several years before the development of HLB symptoms in plants. The study suggests that discount garden centers and retail nurseries may have played a significant role in the widespread distribution of psyllids and plants carrying HLB pathogens in Florida.

distribution and characterization of citrus tristeza virus in south florida following establishment of toxoptera citricida
Plant Disease, 2004Co-Authors: Susan E Halbert, R F Lee, Hanife Genc, Bayram Cevik, Lawrence G Brown, I M Rosales, K L Manjunath, Mark Pomerinke, D A Davison, C L NiblettAbstract:Halbert, S. E., Genc, H., Cevik, B., Brown, L. G., Rosales, I. M., Manjunath, K. L., Pomerinke, M., Davison, D. A., Lee, R. F., and Niblett, C. L. 2004. Distribution and characterization of Citrus tristeza virus in south Florida following establishment of Toxoptera citricida. Plant Dis. 88:935-941. The incidence of Citrus tristeza virus (CTV) was found to increase significantly in southern Florida within 2 years after the establishment of its most efficient vector, Toxoptera citricida (Kirkaldy). Increased incidence of both mild and severe strains was documented, with the incidence of severe strains increasing more than mild strains. Molecular probes capable of differentiating mild, quick decline and various types of stem-pitting strains demonstrated that trees often were infected with more than one strain of CTV, with trees containing up to five different strains. Some CTV strains detected in the southeast urban corridor of Florida and in commercial groves in southwest Florida were found to react with probes specific for stem-pitting strains known from elsewhere in the world. The implications of the presence of these CTV strains in Florida and their possible presence in citrus budwood scion trees are discussed.

Combining multiple precision-boosted classifiers for indoor-outdoor scene classification
'University of Otago Library', 2011Co-Authors: Da Deng, Zhang JianhuaAbstract:Along with the progress of the content-based image retrieval research and the development of the MPEG-7 XM feature descriptors, there has been an increasing research interest on object recognition and semantics extraction from images and videos. In this paper, we revisit an old problem of indoor versus outdoor scene classification. By introducing a precision-boosted combination scheme of multiple classifiers trained on several global and regional feature descriptors, our experiment has led to better results compared with conventional approaches.UnpublishedA.W.M.

Image saliency mapping and ranking using an extensible visual attention model based on MPEG-7 feature descriptors
'University of Otago Library', 2011Co-Authors: Wolf Heiko, Da DengAbstract:In visual perception, finding regions of interest in a scene is very important in the carrying out visual tasks. Recently there have been a number of works proposing saliency detectors and visual attention models. In this paper, we propose an extensible visual attention framework based on MPEG-7 descriptors. Hotspots in an image are detected from the combined saliency map obtained from multiple feature maps of multi-scales. The saliency concept is then further extended and we propose a saliency index for the ranking of images on their interestingness. Simulations on hotspots detection and automatic image ranking are conducted and statistically tested with a user test. Results show that our method captures more important regions of interest and the automatic ranking positively agrees to user rankings.UnpublishedL. Itti and C. Koch.

Content-based image collection summarization and comparison using self-organizing maps
'University of Otago Library', 2011Co-Authors: Da DengAbstract:Progresses made on content-based image retrieval has reactivated the research on image analysis and similarity-based approaches have been investigated to assess the similarity between images. In this paper, the content-based approach is extended towards the problem of image collection summarization and comparison. For these purposes we propose to carry out clustering analysis on visual features using self-organizing maps, and then evaluate their similarity using a few dissimilarity measures implemented on the feature maps. The effectiveness of these dissimilarity measures is then examined with an empirical study.UnpublishedC. Carson, M. Thomas, S.

How interesting is this? Finding interest hotspots and ranking images using an MPEG-7 visual attention model
2011Co-Authors: Wolf Heiko, Da DengAbstract:A lively Dunedin street scene, and a panoramic view of the Southern Alps - two images that might appeal and interest a viewer. But where do people look, and which of those images appears more interesting? In this paper, we are introducing a visual attention model based on MPEG-7 descriptors that creates multi-scale feature maps to detect interest hotspots in images. Further, we are assessing three methods that use attention models for image ranking and compare them to results gathered in a user test. Preliminary results indicate that rankings created by our model show a high agreement with rankings obtained in a pilot user study.PublishedNon Peer ReviewedCastano, R., Wagstaff, K., Song, L. & Anderson, R.
