The medical image has become a diagnostic technique largely applied for the determination of doctor's diagnosis. But it is difficult for detecting the medical image borders accurately. This paper proposes a new medical image edge-detection technique based on PSO Algorithm. A new fitness function is formulated as the objective function. PSO algorithm is adopted to find the optimal filter mask to enhance...
In order to solving segment text accurately and robustly from a video sequences. This paper presents a new approach for text segmentation in video sequences by using recursive particle filter. This approach presents a probabilistic algorithm for segmenting text in video sequences based on adaptive thresholding using a Bayes filtering method. First, we describe adaptive mixture model for video text...
In order to determine the optimal thresholds in image segmentation, an effective image threshold segmentation method is presented that base on Fuzzy logic. A new fuzzy entropy is defined, that is not only related to the membership (fuzzy domain) but also related to the probability distribution (space domain), it can respond to the variety of image input information. In addition, by introducing a novel...
Image processing has to deal with many ambiguous situations. Fuzzy set theory is a useful mathematical tool for handling the ambiguity or uncertainty. In order to apply the fuzzy theory, selecting the fuzzy region of membership function is a fundamental and important task. In this paper, a new method of membership function based on fuzzy theory by PSO algorithm optimized was proposed by analyzing...
