Image Analysis Tool with Laws' Masks to Bone Texture

摘要

Osteoporosis is considered as a major public health threat. It affects the bones and is caused by the decrease of the tissue that forms it, both of the proteins that constitute its matrix or structure and the mineral salts of calcium it contains, so the bone is less resilient and more fragile than normal, has less resistance to falls and breaks with relative ease after trauma, resulting in fractures or micro fractures. This paper presents a simple yet efficient image processing approach by proposing a new image feature detector and descriptor based in LAẂs filter. Images of the hip area were evaluated, being the part where they present major problems due to osteoporosis (more frequently in women older than 40).
