Abstract

Segmentation is basic process in image processing. It always produces an effective result for next process. In this paper, we proposed the flower image segmentation. Oxford flower collection is used for segmentation.Different segmentation techniques are available. Different techniques and algorithm are developed to describe the segmentation.We proposed a OTSU thresholding technique for flower image segmentation in this paper. which gives good result as compared with the other methods and simple also.Segmentation subdivide the image into different parts.firstly, segmentation techniques and then otsu thresholding method described in this paper.CIE L*a*b color space is used in thresholding for better results.Thresholding apply seperatly on each L, a and b component. accordingly the features can be extracted like shape, color, texture etc. finally, results with the flower images are shown.

Keywords: Otsu thresholding, segmentation, CIE Lab color space, Region based segmentation, globle thresholding method.

Abstract

Construction of tall buildings, both residential and commercial are in insistance. In case of tall structure high lateral forces develops due to earthquake load and wind load are crucial. Thus the effects of lateral loads needs consideration for strength and stability of the structures. In tall buildings, lateral loads are critical as it increases drastically after a certain height of the structure. Shear wall systems are one of the most commonly used dynamic load resisting systems in high-rise buildings which help in achieving strength and stability along with economy. In this study, an attempt has been carried out to check the dynamic stability of a tall residential structure by applying variations symmetric arrangement of the shear wall. The Case study of a 26 storied RCC structure situated in Pune region of Maharashtra, India has been carried out. The effect of location of shear wall on dynamic behaviour of building is analysed using ETABS software using response spectrum method for earthquake analysis and IS875 (III) for wind analysis. The proposed position of shear wall gives the effective results as compare to other position.
