<p>[QUOTE=&quot;GDJMSP, post: 3909582, member: 112&quot;]I&#039;m a bit confused here John. In your 1st comment you&#039;re suggesting that he filter out luster in the pics so it does not influence the training. But in your 2nd comment you are acknowledging that luster is required in order to grade the coin. </p><p><br /></p><p>So, if quality of luster must be used to grade the coins, how&#039;s his software supposed to figure out what the coins grade if luster is filtered out of the pics ? </p><p><br /></p><p>[USER=27272]@tlasch[/USER] </p><p><br /></p><p>I see a few problems with your idea. Contrary to what John suggested above, it seems to me that using pics from various sources is going to skew the data being used for learning because of inconsistencies and differences in the pics from various sources. Even if you only use 1 outside source there are going to be inconsistencies in the pics. </p><p><br /></p><p>I think another problem is going to be the differences in grading between the TPGs as none of them grade coins by the same standards. And to further compound the problem, all of them have changed their grading standards over the years - so the grades themselves, from each TPG, are going to be inconsistent based on when each was graded.</p><p><br /></p><p>Bottom line, I do not see how your idea, as you&#039;re suggesting it be done, could ever work because of all the differences and inconsistencies in your source material and multiple grading standards that are all different from each other.</p><p><br /></p><p>The only way I could ever see it working would be if you yourself could take high quality pics of each coin, making sure that each pic is consistent so the software can use those pics for grading. And then input your own grading standards criteria into the program so the program can determine the grade based on what you have given it. And of course you&#039;re gonna have to write your own code so the program can do that. </p><p><br /></p><p>All of this is the problem with computer grading and why it doesn&#039;t work - can&#039;t work.[/QUOTE]</p><p><br /></p>
