SGHA Research ~ Photograph analysis ~ Photo DSCF0105 New Mexico State Penitentiary, Old Main

A digital image can be treated as a data set to extract information. This is the information that we extracted from a digital photograph taken during a investigation at the New Mexico State Penitentiary.

Before and After Photos

1. Thermal Analysis When an psuedo-thermal filter is applied to the photograph, several darker sections appear that are not easily seen in the original photograph. The darker regions would represent cooler sections within the photograph. The regions exist just below and on the upper left side of the ecilpse. There appears to be an effect of thermal equilibrium. In 1900 the physicist Max Planck found the law that governs the emission of electromagnetic radiation from a black body in thermal equilibrium. More specifically Planck’s law gives the energy stored in the electromagntic field in a unit volume and unit frequency range, [f, f +df ]with df =1Hz , when theelectromagnetic field is in thermal equilibrium with its surrounding that is at temperature T. A black body is simply defined as an object that absorbs all light. In subsequent scan analysis, the background in the center of the ecilpse is blocked out and not visible at certain wavelengths. Could this be the black body some sort of electromagnetic phenomena?

Note: It should be noted that the estimate of temperature variance is based solely upon the analysis of the photograph.

A digital image can be treated as a data set to extract information. Each pixel's intensity value is a measure of how much energy was used to generate it within the band of spectrum used to produce the image. The sum of the pixel intensities is a measure of the total energy used to create the whole image.The highest output of energy from the object in the photograph is the dark sections moving towrds the eclipse. The Sesmimetric value of the draker region is estimated at -52.

The simulated spectrum analysis shows the objects intensity is simiar to it's surroundings. When a simulated high UV bandpass filter (Figure 3) is applied to the photograph, the "glow" in the corners near the eciplse become more visible, indicating that it may be within or near that range.
