Object proposal aims to locate category-independent objects in a given image with a limited number of object candidates indicated by bounding boxes, which can be served as a fundamental of various multimedia applications. Current evaluation criteria based on recall cannot reveal the real abilities of different object proposal methods in objectness measurement. In this paper, we propose a novel object proposal evaluation criterion instead of recall, named objectness measurement ability (OMA). We first analyze the probability to hit an object by non-repetitive random sampling (HPRS), and provide an algorithm for calculating HPRS efficiently. Based on HPRS, we define OMA and extend three commonly used object proposal evaluation criteria by replacing recall with OMA. We evaluated six typical object proposal methods using recall based criteria and OMA based criteria on the test data of PASCAL VOC 2007 and PASCAL VOC 2012. The experimental results show that OMA based criteria can provide more stable evaluation results than recall based ones in revealing objectness measurement ability.
