Developing analytical applications for IoT based on sensor signal processing tends to be complicated as applications are executed as sequence of steps comprising of multiple alternative algorithms, including suitable feature extraction modules depending on the goal of the application. Experience shows that developers spend considerable time and effort in(More)
Semantic representation of sensor, its features, capabilities, location etc. is useful for different stakeholders of a cyber physical system. Semantic Sensor Network (SSN) ontology is one such efficient representation that captures important facets of a sensor. Taking energy meter as an example sensor, our tool SensXplore shows how sensor manufacturers,(More)
—Word spotting is an important recognition task in historical document analysis. In most cases methods are developed and evaluated assuming perfect word segmentations. In this paper we propose an experimental framework to quantify the effect of goodness of word segmentation has on the performance achieved by word spotting methods in identical unbiased(More)
—Digital libraries store images which can be highly degraded and to index this kind of images we resort to word spotting as our information retrieval system. Information retrieval for handwritten document images is more challenging due to the difficulties in complex layout analysis, large variations of writing styles, and degradation or low quality of(More)
