Which the maximum inter-class variance as the genetic algorithm fitness function, the maximum inter-class variance method is very sensitive to noise and the target size, the use of times as the genetic algorithm fitness function will enable better image segmentation results, and effective suppressio...

An improved method of maximum inter-class variance (OTSU) combined with morphological operations is proposed. First, the original CT image is preprocessed by filtering, denoising, image enhancement, and adaptive threshold binarization; then the connecting area marker obtains the outline, using OTSU-...
The class maximum variance ratioTarget featureThis paper presents a method for inter-class ceramic crack detection threshold than the maximum variance within the class-based segmentation. Ceramics crack detection methods are mainly obtained by ceramic image data, image pre-processing, image segmentation,...
This paper proposes an image binarization algorithm based onmaximal variance, which divides an image object into two classes and obtains its best threshold when the separation level between the inter-class variance and intra-class variance is maximal. ...
In addition, the inverse of the Hessian matrix, usually estimated as the matrix of second derivatives of the log likelihood with respect to the parameters in the model, gives an estimate of the asymptotic variance–covariance matrix of the parameters. Hence, the square root of the diagonal ...
We describe an algorithm for generating fiber-filled volume elements for use in computational homogenization schemes which accounts for a coupling of the f
1) minimizing the MMD equals to maximize the source and target intra-class distances respectively but jointly minimize their variance with some implicit weights, so that the feature discriminability degrades; 2) the relationship between the intra-class and inter-class distances is as one falls, ano...
This delay variance can take two forms: delay jitter and delay skew. Jitter implies that in an object stream, the actual presentation times of various objects shift with respect to their desired presentation times. The effect of jitter on an object stream is shown in Figure 7.3. In Figure ...
Image image threshold selection using genetic algorithms, which select the fitness function to improve, the use of the maximum inter-class variance as fitness function for the threshold selection process. Because the maximum inter-class variance method sensitive to noise and the target size. And inf...
