Latent prints are not readily visible to the naked eye. As a result, these hidden prints must be developed in some way to increase their visibility and contrast. The most common method of developing latent prints on nonporous objects is to physically enhance them by applying fingerprint powder.
The Crystal Ball by John William Waterhouse (1902, oil on canvas). Scrying (also called seeing or peeping) is the practice of looking into a translucent ball or other material with the belief that things can be seen, such as spiritual visions, and less often for purposes of divination or fortune-telling.ne method of scrying using a crystal ball involves a self-induced trance. Initially, the medium serves as a focus for the attention, removing unwanted thoughts from the mind in the same way as a mantra. Once this stage is achieved, the scryer begins a free association with the perceived images suggested.
From Wiki.GIS.com. Kriging is a group of statistical techniques to interpolate the value of a random field (e.g., the elevation, z, of the landscape as a function of the geographic location) at an unobserved location from observations of its value at nearby locations.riging belongs to the family of linear least squares estimation algorithms. As illustrated in Figure 1, the aim of kriging is to estimate the value of an unknown real-valued function, , at a point, , given the values of the function at some other points, .
