    Initial Contour (IC) is the essential step in level set image segmentation methods due to start the efficient process. However, the main issue with IC is how to generate the automatic technique in order to reduce the human interaction and moreover, suitable IC to have accurate result. In this paper a new technique which we called Morphological Region-Based Initial Contour (MRBIC), is proposed to overcome this issue. The idea is to generate the most suitable IC since the manual initialization of the level set function surface is a well-known drawback for accurate segmentation which has dependency on selection of IC and wrong selection will affect the result. We have utilized the statistical and morphological information inside and outside the contour to establish a region-based map function. This function is able to find the suitable IC on images to perform by level set methods. Experiments on synthetic and real images demonstrate the robustness of segmentation process using MRBIC method even on noisy images and with weak boundary. Furthermore, computational cost of segmentation process will be reduced using MRBIC

    A sustainable livelihood framework to implement CSR project in coal mining sector

    Corporate social responsibility (CSR) in mining areas has increased momentum especially in countries like India where it has been made mandatory. The primary objective of this paper is to document actual social challenges of mining in field areas and find out how companies in the coal sector can work in a systematic manner to achieve uplift of affected communities. The first part of the paper draws evidence from three different bodies of literature, i.e. CSR and coal mining, capacity building and livelihood generation in mining areas. We try to converge the literature to propose a novel framework for livelihood generation work through capacity building with the help of CSR investments. The paper also documents a live case of planning and the implementation of capacity building activities in Muriadih coal mines in the Jharkhand state of India and offers lessons to both business and policy makers. The proposed framework has only been experimented in a local context, yet has the potential to be replicated in other mining areas
