Probabilistic rand index
Webb23 sep. 2005 · We show that the measure has a clear probabilistic interpretation as the maximum likelihood estimator of an underlying Gibbs model, can be correctly normalized to account for the inherent similarity in a set of ground truth images, and can be computed efficiently for large datasets. Webb1 aug. 2024 · Each method has its own advantages and disadvantages. It is important to explore the properties of these algorithms. According to the work in Ref. [1] the following properties are desired for superpixel segmentation: 1. Accuracy. Accuracy measures how superpixels adhere well to the image boundaries.

Webb19 juni 2024 · The probabilistic Rand (PR) index has the following three problems: It lacks variations in its value over images; the normalized probabilistic Rand (NPR) index to address this is theoretically unclear, and the sampling method of pixel-pairs was not proposed concretely. In this paper, we propose methods for solving these problems. Webb16 juli 2024 · The Rand index or Rand measure (named after William M.

Webb20 juli 2009 · In this paper, we introduce a fuzzy extension of the Rand index, a well-known measure for comparing two clustering structures. In contrast to an existing proposal, which is restricted to the comparison of a fuzzy partition with a non-fuzzy reference partition, our extension is able to compare two proper fuzzy partitions with each other.
