Abstract-Millions of surveillance cameras operate at 24x7 generating huge amount of visual data for processing. However, retrieval of important activities from such a large data can be time consuming. Thus, researchers are working on finding solutions to present hours of visual data in a compressed, but meaningful way. Video synopsis is one of the ways to represent activities using relatively shorter duration clips. So far, two main approaches have been used by researchers to address this problem, namely synopsis by tracking moving objects and synopsis by clustering moving objects. Synopses outputs, mainly depend on tracking, segmenting, and shifting of moving objects temporally as well as spatially. In many situations, tracking fails, thus produces multiple trajectories of the same object. Due to this, the object may appear and disappear multiple times within the same synopsis output, which is misleading. This also leads to discontinuity and often can be confusing to the viewer of the synopsis. In this paper, we present a new approach for generating compressed video synopsis by grouping tracklets of moving objects. Grouping helps to generate a synopsis where chronologically related objects appear together with meaningful spatio-temporal relation. Our proposed method produces continuous, but a less confusing synopses when tested on publicly available dataset videos as well as in-house dataset videos.
Goat dermatitis was first reported in India by Haddow and Idnani (1948). An outbreak of the disease occurred in eastern India in the winter of 1982 to 83. The disease was goat-specific and did not affect sheep reared nearby. There was high fever with a body temperature of up to 106~ generalised eruption of papules in the ~kin all over the body, in the lips, gum and tongue and in the interdigital spaces. The papules soon developed into hard and thickened nodules measuring 0-5 to 1-0 cm in diameter but did not form exudative pustules. There were mucopurulent oeular and nasal discharges and bilateral corneal opacity. The nodules later decreased and fell off leaving a raw ulcer except in the mouth and interdigital spaces where they tended to ulcerate. Morbidity was 100% and mortality 50%. The disease spread rapidly within the flock and was carried to neighbouring flocks probably through fomites. The virulence was equally exhibited in the adults and the young.Nodules from the skin of affected goats were collected at the height of reaction in Phosphate Buffer Saline (pH 7.2) with penicillin and streptomycin added and forwarded to the Animal Virus Research Institute, Pirbright, England for virological study. Post-mortem examination of dead goats was made and pieces of tissue from various organs with lesions were collected in 10% formol saline for histopathological study.The affected goats were treated with intravenous injections of oxytetracycline at the rate of 25 mg per kg body weight daily for five to eight consecutive days along with antiseptic dressing of ulcers and supportive therapy with dextrose saline, vitamins, etc. to the convalescing goats. Medicinal therapy affected recovery in 50% of the goats.The virological study revealed a pox virus measuring 330 • 300 millimicrons. Post-mortem examination of dead goats revealed yellowish white nodules measuring 0.5 to 1.0 cm in diameter in the epithelium of the rumen, abomasum and lung parenchyma. There was fibrino purulent pleuritis and pneumonia in all dead goats. In some there was also fibrinous pericarditis. In a few kids the heart revealed small whitish loci in the epicardium extending into the myocardium.Although goat dermatitis simulates goat pox in many respects it is distinguishable from the latter by the thick and rubbery rather than exudative nature of the skin nodules and high virulence. The causative virus is alleged to differ from goat pox virus in virulence but it has not been accepted as yet as a valid species (Matthews, 1982).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
