1. Do you consider the pictures and videos on your data page to be evidence of the paranormal?

No. In fact the things found by ghost hunters and paranormal investigators / researchers are not even sufficient to be called evidence. So, it is a term we do not use. Data is the most correct word to describe what is collected. A look at the common meanings of each word reinforces this idealogy (definitions from Wikipedia).

Evidence

Evidence in its broadest sense includes everything that is used to determine or demonstrate the truth of an assertion. Giving or procuring evidence is the process of using those things that are either a) presumed to be true, or b) were themselves proven via evidence, to demonstrate an assertion's truth. Evidence is the currency by which one fulfills the burden of proof.

There are many issues that surround evidence, making it the subject of much discussion and disagreement. In addition to its subtle nature, evidence plays an important role in many academic disciplines, including science and law, adding to the discourse surrounding it.

An important distinction in the field of evidence is that between circumstantial evidence and direct evidence, or evidence that suggests truth as opposed to evidence that directly proves truth. Many have seen this line to be less-than-clear and significant arguments have arisen over the difference.

Data

Data refers to a collection of facts usually collected as the result of experience, observation or experiment, or processes within a computer system, or a set of premises. This may consist of numbers, words, or images, particularly as measurements or observations of a set of variables. Data is often viewed as a lowest level of abstraction from which information and knowledge are derived.

2. What is in this photographic data?

What is captured on a X-Spectrum camera is very debatable. One hypothesis suggests infrared plasma while another suggests that the abnormalities are photographic artifacts that are created by looking at gases or other known phenomena in the extended spectrums of infrared and ultraviolet light simultaneously. There are many other hypotheses as well, but the idea is to look for possible visible components of various types of energy.

3. What is an X-Spectrum camera?

An X-Spectrum camera is a digital camera that has had its components modified so that it takes full advantage of the spectral abilities of its' CCD. Typical examples would be removal of the IR-Cut filter behind the lens and the UV cut coatings on the lens itself. X-Spectrum cameras can photograph light deep into the IR and UV portions of the spectrum.

4. What is image analysis software?

Image analysis is the extraction of meaningful information from images; mainly from digital images by means of digital image processing techniques. Image analysis tasks can be as simple as reading bar coded tags or as sophisticated as identifying a person from their face.

Computers are indispensable for the analysis of large amounts of data, for tasks that require complex computation, or for the extraction of quantitative information. On the other hand, the human visual cortex is an excellent image analysis apparatus, especially for extracting higher-level information, and for many applications, including medicine, security, and remote sensing, human analysts still cannot be replaced by computers. For this reason, many important image analysis tools such as edge detectors and neural networks are inspired by human visual perception models.
