It is commonly known that search engines are currently incapable to identifying objects or content within the image and although there has been much work recently for computers to perform this work, the technology is not quite there. This problem leads to one of the most common questions we see pertaining to the value of image or photo tagging. The answer to this question depends on the solution you are seeking. General users with personal image collections have different needs than those of enterprise customers but the problem (and solution) is the same.
Personal
Personal or power users typically have growing collections of images that are stored in a flat directory structure. Unless they are disciplined or exact about how those images are stored and cataloged, images are stored by date and maybe by event. However, most users don’t go so far as to change the image naming structure so even when they are organized by date, there is no detail on what is in the photo. What they end up with is a bunch of images with file names like “DSC001248.jpg.” Not very descriptive to say the least! What this means to the user is if they want to find all pictures of their daughter, they must rely on their memory or spend time looking through thumbnail images to find images they are searching for. While this may be a viable solution, it is not very practical as their collection grows from 100’s to 1000’s of digital images over time.
Enterprise
Enterprise customers have a similar problem except theirs can cost them money. Enterprises have large collections of images that are stored in repositories. Although they tend to do a better job at renaming their images with names that relate to the content in the image, it is not practical to list out every detail in the image and include that in the file name. Alternatively, some enterprise customers will create elaborate directory structures to account for the insufficiency in identifying image content. However, as the repositories grow, enterprise customers are faced with an ever growing collection of images that are essentially lost or undiscovered because of the shear number of images in the repository. This can cost a company sales especially if a customer is unable to find a particular piece of art, for example.
So what can they do. Tagcow was started to address this issue. Instead of waiting for the technology to arrive to discover the content within an image, we approached the problem from a human point of view. Humans are uniquely qualified to identify the content in an image and will, for the foreseeable future, be able to add tags, such as human emotions, that computers will find difficult to ever tag. That said, image tags will empower users, personal and enterprise, to search their images or photos in a way never before possible: by content.
