For example, the size of the object may be calculated using the images, the associated focal lengths of a digital camera that acquired the images, and the law of cosines. Using the scale of the object, an image of the object may be appropriately scaled so that it can be combined with ...

Hexagon is a six sided two dimensional figure or it is a closed polygon made up of six line segments. Learn about the real life objects of hexagonal shapes and its parameters, at BYJU’S.
Medical image segmentation is crucial in diagnosing and treating diseases, but automatic segmentation of complex images is very challenging. Here we present a method, called the crack propagation method (CPM), based on the principles of fracture mechanic

In [30], a method based on the law of cosines with a box–whisker plot is proposed, which outperforms the conventional CD methods. Although the OBCD methods can utilize the spatial feature information of HR remote sensing images, the traditional manual feature extraction is more complicated and...
μ0 and μ are the cosines of the incidence and emission angles. We assume that the azimuth of illumination direction I is 270°, the elevation angle is 45°, and the camera direction C is perpendicular to the surface level. η(k, l) indicates the surface normal. μ0 and μ are ...
The sensor zenith angle (PS_zen) was calculated as the angle between each pixel, the focal point, and the nadir pixel by applying the law of cosines in Equation (3): 𝑃𝑆_𝑧𝑒𝑛=𝑎𝑟𝑐𝑐𝑜𝑠 (𝐹𝑃2+𝐹𝑁2−𝑁𝑃22·𝐹𝑃·𝐹𝑁)PS_zen=arccos (FP2...
The discrete cosine transform DCT is a variation of the discrete Fourier transform, where the image is decomposed into sums of cosines, but using real numbers only. It only acts on periodic functions with even symmetry and the result is a sequence of real numbers. In Equation (1), the char...
