“…In addition, the neurons with similar intensity always fire synchronously. In view of these advantages, PCNN has been widely applied to image segmentation [25][26][27][28]. In this paper, we segment ROI into a binary image via the SPCNN (simplified PCNN) whose working principle is described in "Appendix."…”

“…In SPCNN, the external input is the normalized image S (obtained by Min-Max normalization), and the series of pulse outputs are the different binary images from which we can pick out the desired segmentation result. For LV segmentation, we set the SPCNN parameters (W, β, V E ) according to [29]: W = [0.5, 1, 0.5; 1, 0, 1; 0.5, 1, 0.5], β = 0.1, V E = 20, and set α e adaptively by using α e = C/mean(S) [28]. C is a constant, and "mean(S)" represents the calculation of the average gray level.…”

“…A PCNN is a novel network that is used in many image processing applications, such as noise removal for gray [17] and color [18] images, image segmentation [19][20][21][22], image smoothing [23], and image enhancement [20,24]. In addition it was successfully explored in many applications such as car plate number detection [25], face recognition [26], and object detection [27].…”

“…So far, thousands of segmentation algorithms have been developed, for which numerous classification methods have been proposed. The traditional image segmentation methods can be classified into the following four classes: (1) threshold-based method [1,2]; (2) edge-based method [3,4]; (3) regionbased method [5,6]; and (4) specific theory-based method [7]. With the development of the artificial neural network, such as fuzzy set theory and graph theory, some novel segmentation algorithms have been proposed in combination with these theories [8][9][10].…”
