DATAVISION: S5000 & S5000i Demo

S6000 Static Image Demo

A free demo and discussion of the S6000 Static Active X COM component is available in a simple to use EXE Demo. In order to run this demo you must first download and install the Topaz S6000 Active X Demo, even if you are only interested in comparing images from paper.

The Series 6000 Static Active X is designed to compare two static images to one another and then produce the probability they match each other.

The Active X is quite simple to implement. Once you instantiate the control, the comparison is activated with the following:

The objective was to develop an API with the following properties:
dApi.SignatureCompare("C:\Temp\20090806.TIF","C:\CLIENTSIGNATURES\1254265.TIF", LnSignatureString)

return dApi.Probability

return dApi.Score

The API accepts images in .bmp, ;tif, .png and .jpg. The images should be in two-bit level, so .jpg may not work well. The first image is the sample that will be compared to the second image, which is the master. The algorithms classify the master image, detect the number of valid features in the master and then compare the sample to the master image. The API will accept a string of integers know as the “Electronic Signature”. If this optional parameter is included in the call, the algorithms will use the string as the source of previous readings, return the results and return an updated Electronic Signature string, which the user should store until the next time this signature master is used in a comparison. The effect of passing the string is to train the algorithms on the master signature, and to improve the likelihood a bad signature will be accepted as good.

Example of a good comparison

Example of a bad comparison

Install the Topaz Demo before running the Static Demo

Copy All Images in the General Demo Folder to the folder "C:\Images"

Add your own images as required. Demo supports .bmp, .tif, .png, .jpg

Important:

An image in one format usually will not match the same image in a different format. For comparison be sure the images are bi-level (0 or 1) only, and be sure they are in the same image format.

The demo gets better through training, but that is not available in this free demo. This demo bases the likelihood a sample image was produced by the same person who produced the master image.

Results may be different if image 1 (sample) is compared to image 2 (master) and then
image 2 (sample) is compared to image 1 (master). This is because the number of valid features detected in the master is used to determine the features tested in the sample.
