In a first stage a cancer promotes an intense process of vascularization at the affected area increasing blood flow and modifying the local temperature of the body. Using a thermal camera, the infrared radiation emitted by the human body can be captured and then used in the measuring of body temperature, turning the results into an image. Moreover, thermography can detect suspicious regions in patients...
Digital images are functions of the brightness values in 2D representations of real-world scenes. The term image processing describes computer operations carried out on digital images with some goal in mind. Such goals are related to application areas in a variety of disciplines, from art and engineering to astronomy and science.
Due to global warming, an increase amount of water could be found in the environment. It causes the appearance of clouds in satellite and aerial image acquisitions. Clouds and shadows cause interference in aerial images acquired, that can be in two ways: signal attenuation and different range of illuminations. The signal attenuation is caused by the image acquisition above the cloud cover, as in the...
Mathematical morphology (MM) is a powerful tool for automatic extraction of grain-sized data from digital images. In many cases, color information can be quite useful for the enhancement of the results obtained. Nevertheless, the definition of color MM, as simple extension of gray level MM, does not work appropriately for granulometry applications. The problem is that fake colors arise in the results...
