Review on CBIR Image Based on Colour, Texture and Shape Features of Biomedical Image Applications
Abstract: This study seeks to understand how different image enhancing methods affect the sensitivity of contrast-based textural measures and morphological traits derived from high-resolution satellite data (three-band SPOT-5). The built-up/non-built-up detection framework is the backbone of every biomedical application. Using supervised learning while working with a low-resolution reference layer reduces uncertainty and boosts the reference layer's quality in a roundabout way. The image's histogram is recalculated based on contrast in order …

Platelets A Tiny Cell Fragments
Abstract: Platelets are disc-shaped, anucleate cells that are approximately 2-3 μm in diameter. Their primary function is to control hemostasis, or blood clotting, but they also play important roles in angiogenesis (the formation of new blood vessels) and innate immunity (the body's first line of defence against infection). With a diameter of just 2-3 microns, platelets are tiny, disc-shaped cells that lack a nucleus. While their main responsibility is to ensure …
