[…] Creating effective algorithms for image search has always been a challenge. You can try seeing how many people link to an image (or the page an image is on) with certain key phrases in the links, you can check alt tags, you can check title tags within an href tag linking the image, you can check surrounding metadata (other data/keywords on the same page as an image), you can read an image’s metadata…but ultimately, you are unable to “see” the image algorithmically. I’ve tried OCR on images with limited success as well as scanning or certain colors and hues to try to help identify images…both with limited success and are also computationally expensive. I’ve even seen other types of image searches such as search by sketch, person (facial recognition), colors, and others but they are also limited for various reasons. It is also the reason why captchas are effective. […]
