It is considered the first commercially successful colour photography process. Autochromes feature a distinctive soft, muted colour palette and a unique pointillist aesthetic, derived from the potato starch granules which make up the autochrome\u2019s colour filter. Today, displaying original autochromes is rare as original autochromes are extremely light sensitive. For this reason, it is common for digital or facsimile versions of autochromes to be presented in exhibitions.<\/p>\n<\/div>\n<p><!-- =========================\n\n\n\n<section class=\"nl-banner\" role=\"region\" aria-label=\"Evaluate\">\n  \n\n<div class=\"nl-banner__inner\">\n    \n\n<h2 class=\"nl-banner__title\">Your opinion matters<\/h2>\n\n\n    \n\n<p class=\"nl-banner__tagline\">Fill the following form and test PERCEIVE Text2Autochrome Tool<\/p>\n\n\n    \n\n<div class=\"nl-banner__actions\">\n      <a class=\"nl-banner__cta\" href=\"https:\/\/perceive.staging.imkitech.com\/text-to-auto-chrome\" target=\"_blank\">Try the tool<\/a>\n      <a class=\"nl-banner__cta\" href=\"https:\/\/forms.cloud.microsoft\/e\/w4C31Gjgta\">Fill in the form<\/a>\n      <a class=\"nl-banner__cta nl-banner__cta--outline\" href=\"#nl-modal\">Show QR Code<\/a>\n    <\/div>\n\n\n  <\/div>\n\n\n<\/section>\n\n\n\n ========================= --><\/p>\n<div class=\"perceive-container\">\n<h6>Utilizing generative AI to generate autochrome images as well as synthetic defects<\/h6>\n<p class=\"custom-font\">Our new approach utilizes advanced generative models to create images that attempt to capture the autochrome\u2019s unique quality. This involves simulating common defects in autochromes like greening and cracking to develop machine learning methods for repair and enhance the quality of generated images. This approach can help us generate synthetic defects (for e.g. images with greening defects) and hence create a dataset of defected and non-defected autochrome image pairs. This would allow us to train an AI model that learns to remove these greening defects and hence potentially restore autochrome defects.<\/p>\n<style id=\"wp_carousel_dynamic_css3430\">#sp-wp-carousel-free-id-3430 .wpcp-swiper-dots {margin: 40px 0px 0px 0px;}.wpcp-wrapper-3430 .swiper-wrapper .swiper-slide-kenburn, .wpcp-wrapper-3430 .swiper-wrapper, .wpcp-wrapper-3430 .wpcpro-row{align-items: center;}#sp-wp-carousel-free-id-3430 .wpcp-single-item {box-shadow: 0px 0px 0px 0px #dddddd;transition: all .3s;margin: 0px;}#sp-wp-carousel-free-id-3430.swiper-flip .wpcp-single-item{margin: 0!important;}#sp-wp-carousel-free-id-3430 .wpcp-single-item:hover {box-shadow: 0px 0px 0px 0px #dddddd;}#sp-wp-carousel-free-id-3430.sp-wpcp-3430 .wpcp-single-item {border: 1px solid #dddddd;}#sp-wp-carousel-free-id-3430.sp-wpcp-3430 .swiper-button-prev,#sp-wp-carousel-free-id-3430.sp-wpcp-3430 .swiper-button-next,#sp-wp-carousel-free-id-3430.sp-wpcp-3430 .swiper-button-prev:hover,#sp-wp-carousel-free-id-3430.sp-wpcp-3430 .swiper-button-next:hover {background: none;border: none;font-size: 30px;}#sp-wp-carousel-free-id-3430.sp-wpcp-3430 .swiper-button-prev i,#sp-wp-carousel-free-id-3430.sp-wpcp-3430 .swiper-button-next i {color: #aaa;}#sp-wp-carousel-free-id-3430.sp-wpcp-3430 .swiper-button-prev i:hover,#sp-wp-carousel-free-id-3430.sp-wpcp-3430 .swiper-button-next i:hover {color: #178087;}#sp-wp-carousel-free-id-3430.sp-wpcp-3430 .wpcp-swiper-dots .swiper-pagination-bullet {background-color: #cccccc;}#sp-wp-carousel-free-id-3430.sp-wpcp-3430 .wpcp-swiper-dots .swiper-pagination-bullet.swiper-pagination-bullet-active {background-color: #178087;} #sp-wp-carousel-free-id-3430.sp-wpcp-3430.wpcp-image-carousel .wpcp-single-item:hover img, #sp-wp-carousel-free-id-3430.sp-wpcp-3430.wpcp-post-carousel .wpcp-single-item:hover img, #sp-wp-carousel-free-id-3430.sp-wpcp-3430.wpcp-product-carousel .wpcp-single-item:hover img{-webkit-transform: scale(1.2);-moz-transform: scale(1.2);transform: scale(1.2);}#sp-wp-carousel-free-id-3430 .wpcpro-row>[class*=\"wpcpro-col-\"] { padding: 0 10px;
