             abstract = "Image segmentation evaluation is usually performed by visual 
                         inspection, by comparing segmentation to a ground-truth, or by 
                         computing an objective function value for the segmented image. All 
                         these methods require user participation either for manual 
                         evaluation, or to define ground-truth, or to embed desired 
                         segmentation properties into the objective function. However, 
                         evaluating segmentation is a hard task if none of these three 
                         methods can be easily employed. Often, higher level tasks such as 
                         detecting or classifying objects can be performed much more easily 
                         than low level tasks such as delineating the contours of the 
                         objects. This fact can be advantageously used to evaluate 
                         algorithms for a low level task. We apply this approach to a case 
                         study on plankton classification. Segmentation methods are 
                         evaluated from the perspective of plankton classification 
                         accuracy. This approach not only helps choosing a good 
                         segmentation method but also helps detecting points where 
                         segmentation is failing. In addition, this more holistic form of 
                         segmentation evaluation better meets requirements of big data 
                         analysis.",
