Valero will focus on three main aspects:</span><span class="gmail-Apple-converted-space" style="caret-color: rgb(38, 38, 38); color: rgb(38, 38, 38); font-family: Karla, sans-serif;"> </span></font></div><p style="box-sizing: border-box; margin-bottom: 1rem; margin-top: 0px; caret-color: rgb(38, 38, 38); color: rgb(38, 38, 38); font-family: Karla, sans-serif;"><font size="4">1) how to build a metric that takes into account the naturalness and the efficiency of the aids while at the same time considering the need to include chromatic adaptation into the simulations used to predict the quality parameters and other aspects that could be taken into account for the quality evaluation;</font></p><p style="box-sizing: border-box; margin-bottom: 1rem; margin-top: 0px; caret-color: rgb(38, 38, 38); color: rgb(38, 38, 38); font-family: Karla, sans-serif;"><font size="4">2) which type of deficiency is more in need of any aid, and how to evaluate this need appropriately;</font></p><p style="box-sizing: border-box; margin-bottom: 1rem; margin-top: 0px; caret-color: rgb(38, 38, 38); color: rgb(38, 38, 38); font-family: Karla, sans-serif;"><font size="4">3) the results of the quality evaluation are quite dependent on the way they are tested, as shown by the different conclusions that can be reached for display-based evaluation and real scenes-based evaluation. </font></p><p style="box-sizing: border-box; margin-bottom: 1rem; margin-top: 0px; caret-color: rgb(38, 38, 38); color: rgb(38, 38, 38); font-family: Karla, sans-serif;"><font size="4">This webinar will offer a unique chance to gather and exchange scientifically-based opinions on the use of colored filters to help CVD subjects, an issue that has clear social repercussions given the prevalence of CVD.<br style="box-sizing: border-box;"><br></font></p><div><font size="4">You can register at:</font></div><div><font size="4"><br></font></div><div><font size="4"><a href="https://osa.zoom.us/webinar/register/WN_YcghiIZCRmyLqr-dWw3Tzw" rel="noreferrer" target="_blank" data-saferedirecturl="https://www.google.com/url?q=https://osa.zoom.us/webinar/register/WN_YcghiIZCRmyLqr-dWw3Tzw&source=gmail&ust=1685129064818000&usg=AOvVaw2jNeTFQDYUxhoek-y4P01V" style="color: rgb(17, 85, 204);">https://osa.zoom.us/webinar/<wbr>register/WN_YcghiIZCRmyLqr-<wbr>dWw3Tzw</a><br></font></div><div><font size="4"><br></font></div><div><font size="4">Hope to see you there!</font></div><font color="#888888"><font color="#888888"><font color="#888888" size="4"><div><br></div><div>-Francisco Imai</div></font></font></font></div><font size="4"><br></font><div class="gmail_quote"></div></div><br></div><font size="4" style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);"><br></font></body></html>
