This method leverages unique physical markings that remain relatively stable throughout an organism&rsquo;s lifetime, making it effective for species with distinct patterns. For instance, <a href="https://www.sharkguardian.org/whale-shark-research">whale sharks</a>, <a href="https://www.earthtoolsmaker.org/projects/trout_identification/">trout</a>, <a href="https://app.fruitpunch.ai/article/2024/02/01/tracking-turtles-how-ai-helps-conservationists-to">turtles</a>, and <a href="https://app.fruitpunch.ai/article/2023/03/23/understanding-seals-with-ai">seals</a> all possess unique spot or scale patterns that lend themselves well to this computer vision approach.</p> <div class="image-carousel" data-carousel-id="species-markings-gallery"> <div class="image-carousel__wrapper"> <ul class="image-carousel__controls controls list-reset" id="species-markings-gallery-controls" aria-label="Carousel Navigation" tabindex="0"> <li class="prev" data-controls="prev" aria-controls="species-markings-gallery" tabindex="-1"> <i class="fa-solid fa-arrow-left-long"></i> </li> <li class="next" data-controls="next" aria-controls="species-markings-gallery" tabindex="-1"> <i class="fa-solid fa-arrow-right-long"></i> </li> </ul> <div class="image-carousel__slider" id="species-markings-gallery" data-items="3" data-items-tablet="2" data-items-mobile="1" data-gutter="20" data-loop="true" tabindex="0"> <div class="image-carousel__slide"> <img src="./images/species/turtle2.png" alt="Turtle" class="no-lightense" loading="lazy" data-caption="Sea turtle with unique shell patterns used for individual identification" data-shadow="true" data-rounded="true" /> </div> <div class="image-carousel__slide"> <img src="./images/species/seal.jpg" alt="Seal" class="no-lightense" loading="lazy" data-caption="Seal with distinctive spot patterns on its fur" data-shadow="true" data-rounded="true" /> </div> <div class="image-carousel__slide"> <img src="./images/species/trout.jpg" alt="Trout" class="no-lightense" loading="lazy" data-caption="Trout displaying unique spot patterns along its body" data-shadow="true" data-rounded="true" /> </div> <div class="image-carousel__slide"> <img src="./images/species/whale-shark2.png" alt="Whale Shark" class="no-lightense" loading="lazy" data-caption="Whale shark with distinctive spot patterns that remain stable throughout its lifetime" data-shadow="true" data-rounded="true" /> </div> </div> </div> </div> <div class="image-lightbox" id="species-markings-gallery-lightbox" aria-hidden="true" aria-modal="true" role="dialog" aria-label="Image gallery"> <div class="image-lightbox__overlay"></div> <button class="image-lightbox__close" aria-label="Close lightbox"> <i class="fa-solid fa-xmark"></i> </button> <button class="image-lightbox__prev" aria-label="Previous image"> <i class="fa-solid fa-arrow-left-long"></i> </button> <button class="image-lightbox__next" aria-label="Next image"> <i class="fa-solid fa-arrow-right-long"></i> </button> <div class="image-lightbox__content"> <img class="image-lightbox__image no-lightense" src="" alt="" /> <p class="image-lightbox__caption"></p>
