Thresholding is a type of image segmentation, where the pixels change to make easier analyze. In bi-level thresholding, in grayscale format transformed into binary format. The traditional methods for thresholding may be inefficient finding best threshold and take longer computation time. Recently, metaheuristic swarm-based algorithms were applied optimization different applications find optimal...

Seagrass ecosystems are coastal with high species diversity, especially fish. Fish diversity determines the abundance of communities based on number species. Detection fish directly (in-situ) and conventionally by catching them requires more energy, costs, relatively needs time. Therefore a computer vision method is needed that can detect well using underwater images. The detection model used M...

Based on the spectral reflection characteristics analysis of muddy coastline in Jiangsu, an improved water index (IWI) combined with Otsu algorithm is proposed to extract coastlines from Landsat Operational Land Imager (OLI) images. The IWI-extracted results are compared those extracted by modified normalized difference (MNDWI), (NDWI), enhanced (EWI), revised different (RNDWI) and automated ex...

In order to reasonably reduce the energy consumption of automotive LCD instrument and improve display quality, a new local dimming algorithm is proposed in this paper. Firstly, gray image input obtained by using maximum principle, then, LED backlight brightness value Otsu method entropy method. The BMA smoothing improved combining bilinear interpolation algorithm, pixel compensation based on lo...
