New topics 3 of 3, since July 27, yesterday» Proposal to remove ability to store color images in Type 17» ie i.e. retain only grey‐scale images» Why? Because mainstream cameras all produce single luminancechannel (from NIR illumination)» Why not? The possibility to compare NIR enrollments with colorsearch images, for example. The color image would be acquiredin the visible.» But interoperability concern would be that you could slip hyperspectralimages into three RGB channels, without knowing whatthey mean.» So keep color: But add text: “If the image is encoded as a colorimage, the illuminant shall be VIS”.
