Abstract A multi-objective optimization model for the problem of gesture segmentation is formulated, and a method of solving the model based on a two-phase estimation of distribution algorithm is presented. When building the model, the positions of a series of pixels are taken as the decision variable, and the differences between the colors of pixels and those of a hand are taken as objective functions.A method of gesture segmentation based on a two-phase estimation of distribution algorithm is proposed according to the correlation among the positions of pixels. The method divides the solution of the problem based on evolutionary optimization into two phases, and uses different estimation of distribution algorithms in different phases. In the first phase, the probability model of candidates is formulated by a number of intervals given the fact that the positions of hand pixels distribute in several intervals. In the second phase, the probability model of candidates is built through a series of segments since the positions of *Manuscript (including abstract) Click here to view linked References hand pixels further distribute around curves. A series of pixels constituting a hand region are obtained based on sampling by the above probability models.The proposed method is applied to 2515 problems of gesture segmentation, and is compared with the existing methods. The experimental results demonstrate the effectiveness of the proposed method.

A Developed Artificial Bee Colony Algorithm Based on Cloud Model

“…In addition, we hope to show the performance of DCABC by Null Hypothesis Significance Testing (NHST) [35,36] in our future work. We only test the new algorithm on classical benchmark functions and have not used it to solve practical problems, such as fault diagnosis [37], path plan [38], Knapsack [39][40][41], multi-objective optimization [42], gesture segmentation [43], unit commitment problem [44], and so on. There is an increasing interest in prompting the performance of DCABC, which will be our future research direction.…”

“…Threshold segmentation is easy to calculate and implement, but it has low fault tolerance and can be easily disturbed by noise. Therefore, it is usually used to preprocess data [3] but not the main steps in image segmentation tasks [4] . Some other traditional methods, such as the k-means algorithm [5] and fuzzy c-means (FCM) algorithm [6] based on clustering [7] , regional competition segmentation method based on the active contour model [8] , and region growing and merging algorithm [9] , can be used.…”

Novel Hand Gesture Alert System

“…Regarding the location of the hand, also known as the hand detection, the authors of [26][27][28] extract the hand from the body using depth indices and by setting a threshold, estimated at a specific moment. The authors of [29,30] used skin color maps, and the authors of [31,32] achieved better segmentation results using both depth thresholding and skin detection (using color). In terms of classification, several CNN-based approaches relied on hand-crafted features [33,34], which can capture information about the silhouette, shape, and structure.…”
