<p>[QUOTE=&quot;acsearch.info, post: 3636229, member: 105839&quot;]Hi everyone,</p><p><br /></p><p>thank you very much for your interest in this new tool and for sharing your experience with it (especially to [USER=84744]@Severus Alexander[/USER], who sent me the link to this thread). I am very glad that some of you already found some provenances and die-links that they were not aware of.</p><p><br /></p><p>Please do not pay too much attention to the score (1 to 10), which is mostly used by the system for sorting. The score does not say anything about how similar two coins (or the same coin on different images) are, but how similar the algorithm thinks the two images are. If you have two images of the same coin, for example, the score can be very low if the lighting is too different. And even if you think the picture is 100% identical, the score can be less than 10 if your query image has another format or size than the image that we&#039;ve used for indexing.</p><p><br /></p><p>This said, the same coin on different images usually has a higher score than different coins with die-links. Thus, we use it for sorting.</p><p><br /></p><p>Regarding [USER=19463]@dougsmit[/USER]&#039;s questions:</p><p><br /></p><p><br /></p><p><br /></p><p>The search can indeed handle small to medium differences in lightning and background. However, in general you will get better results if you use a white background with no texture and very natural lighting with decent shadows, as is written in the usage instructions.</p><p><br /></p><p><br /></p><p><br /></p><p>It strongly depends on the quality of the cast and any possible alterations. If it&#039;s a good cast, it certainly will find it.</p><p><br /></p><p><br /></p><p><br /></p><p>Again, it strongly depends on the degree of cleaning or any other alteration. I often use it before I buy a coin (especially gold) in order to see if the coin was altered (e.g. plugged holes, etc.). Here&#039;s a great example:</p><p><br /></p><p><a href="https://www.acsearch.info/search.html?id=5714978" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.acsearch.info/search.html?id=5714978" rel="nofollow">https://www.acsearch.info/search.html?id=5714978</a></p><p><a href="https://www.acsearch.info/search.html?id=3104461" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.acsearch.info/search.html?id=3104461" rel="nofollow">https://www.acsearch.info/search.html?id=3104461</a></p><p><br /></p><p>If you search for the image in the first link, you will certainly find the second entry.[/QUOTE]</p><p><br /></p>
