Magnetic resonance imaging (MRI) creates detailed images by combining a powerful magnetic field with high-frequency radio waves. MRI need to increase brightness and contrast facilitate distinguishing diseases. This study aims improve the depending on suggested algorithm, including three main stages. The first is divide image into areas using Multilevel thresholds then CLAHE for each area separately. Finally, these combine form one it again. By analyzing results calculating non-referenced quality measures, proposed method obtained best compared rest of methods rates EN(6.14), AG(6.79), CEM(0.84), which indicates excellent success in increasing clarity those images.

Waterway transportation is a crucial mode of transportation, but ensuring navigational safety in waterways requires effective guidance ships by the Water Resources Bureau. However, supervisors may only be interested ship portion complex image and need to quickly obtain relevant information. Therefore, this paper proposes two-dimensional OTSU inland multi-threshold segmentation algorithm based on improved genetic algorithm. The enhances search accuracy efficiency, improving thresholding reducing time complexity. Experimental verification shows has excellent evaluation indexes can achieve real-time images. This method not address challenges navigation environments difficult acquisition target data sets, also applied optimization problems other fields combining various metaheuristic algorithms.

This paper investigates a method for the multi-threshold segmentation of grayscale imaging using local minimum points histogram curve as threshold. By smoothing and judging conditions, expected peaks valleys are identified, corresponding used thresholds to achieve fast image segmentation. Compared OTSU (maximum between-class variance) region growing method, this has less computational complexity. In recognition process solder pads with adhesion underfill in LED Chips, time is than one percent that method. The effect better it can images. Moreover, strong adaptability differences overall images, meeting requirements high UPH (Units Per Hour) industrial production lines.
