In order to achieve the detection and recognition of road obstacles and aiming at backgrounds existing in the image target segmented by traditional Otsu algorithm, this paper presents an improved multi-threshold segmentation method based on multi-threshold Otsu algorithm. Due to multi-threshold ...

The algorithm reduces the search range effectively and optimizes the calculation of means and variances using lookup table. Experimental results show that the segmentation speed of the algorithm is greatly improved compared with the traditional multi-threshold Otsu method, and the algorithm can not ...

The two-dimensional (2D) Otsu algorithm used in image segmentation considers both the gray scale information of the image and the spatial information contained in the neighborhood of pixels. The algorithm is quite effective, but a number of variations have been proposed to improve its performance....
