Hi

I want to know the disadvantages and advantages of different segmentation algorithms like

Otsu's multiple thresholds, kmeans, Expectation maximization, mean shift algorithm, normalized cuts etc.

Can anyone share me the source where I can find all the information about these segmentations. And also I want proper images to demonstrate the advantages and disadvantages of one algorithm with another

Common approach: Berkeley Segmentation Dataset (BSDS300) [1] using the precision-recall framework introduced in [2]. Taken from [3].

The BSDS300 consists of 200 training and 100 test images, each with multiple ground-truth segmentations.

An extension of the BSDS300 is created (BSDS500) [3]. It is is an extension of the BSDS300, where the original 300 images are used for training / validation and 200 fresh images, together with human annotations, are added for testing. Each image was segmented by five different subjects on average. Performance is evaluated by measuring Precision / Recall on detected boundaries and three additional region-based metrics.
