Image segmentation is referred to as one of the most important processes of image processing. Image segmentation is the technique of dividing or partitioning an image into parts, called segments. It is mostly useful for applications like image compression or object recognition because for these types of applications, it is inefficient to process the whole image. So, image segmentation is used to segment the parts from the image for further processing. Semantic image segmentation is a vast area for computer vision and machine learning researchers. Many vision applications need accurate and efficient image segmentation and segment classification mechanisms for assessing the visual contents and perform real-time decision making. In this paper, we recommend conditional random field (CRF) based framework for weakly supervised semantic segmentation. First merging super pixels into large pieces and use these pieces for further use to identify objects. The pieces from all the training images are gathered and associated with appropriate semantic labels by CRF. In the case of testing, by using the potential energy of each piece merged from super pixels are compare with piece library. For results, we use commonly used the dataset for image segmentation is MSRC-21 and VOC 2012 with state-of-art.
