RTS-ELM: an approach for saliency-directed image segmentation with ripplet transform

Abstract: In spite of great advancements in the field of computer vision in recent times, efficient identification of salient regions in an image/scene and applying the results to image segmentation are a fertile area to be explored by researchers. This paper deals with a novel approach for image segmentation called RTS-ELM which uses cues from salient region identification. Initially, salient regions of an image are identified using ripplet transform. Based on the saliency map, a trimap is generated for an image which highlights the dominant regions of an image. Using histogram analysis, the dominant pixels of foreground and background are grouped together to produce the positive and negative groups of training data. The salient regions are then segmented using the trained ELM classifier. After a rigmarole process of comparing with eleven extant approaches using three benchmark datasets, RTS-ELM is found to be an efficient method for reifying effective segmentation in different types of images with only a few errors.

Gas Hold up in Multiple Impeller Agitated Vessels

Abstract: Gas hold up was measured in mechanically agitated vessels fitted with dual impellers. Different impellers like Pitched blade turbine and Disc turbine were used. 5 different combinations of dual impellers were used. A tank of 0.45 m internal diameter with an impeller diameter of 0.15m was used. Superficial gas velocity was varied from 0.005m/sec to 0.01 m/ sec. Correlations are proposed for gas hold ups for different combinations of impellers. Optimum combination of dual impellers for maximum gas hold up has been identified. The effect of bottom clearance, inter impeller clearance and physical properties like surface tension on gas hold up were also studied for the optimum combination of impellers

Mass transfer kinetics during osmotic dehydration of amla (Emblica officinalis L.) cubes in sugar solution

Abstract: A four factors three level Box-Behnken response surface design was employed in this study to investigate and optimize the effect of process variables (osmotic solution concentration, fruit to liquid ratio, temperature and dehydration time) on mass transfer properties such as weight reduction, solute gain, water loss, rehydration ratio, shrinkage and overall acceptability of the osmotically dehydrated amla cubes. The cubes of uniform size (10 mm × 10 mm × 10 mm) were impregnated into sugar solution of different solution concentration (30-50° Brix), temperature (30-50°C), fruit to liquid ratio (1:5 - 1:15 g/ml) and time (30-180 min). It was observed from the results that the process variables have significant effect on osmotic dehydration process. The optimum condition was found to be: sugar concentration of 50° Brix, solution temperature of 30°C, fruit to liquid ratio of 1:5 g/ml and immersion time of 133 min. respectively. The microstructural changes during osmotic dehydration were also investigated using scanning electron microscopy (SEM).
