Visual search in the simplest terms is searching something using its visuals whether done by human beings with their eyes or by a machine i.e. computer vision. Search on the internet has come a long way from text, voice based, image search to finally visual search.
In text search, the search is purely based on the keywords which users are inputting. One should narrate the characteristics of the image which one wants to search on the internet. In some cases it is a difficult task to express the characteristics of an image in words. Voice search was introduced to increase the ease by eliminating the boring keyboard typing and allowing users to search the web using spoken voice commands.
Image search by google was introduced on July 12, 2001 due to a demand for pictures of Jennifer Lopez’s green Versace dress that the regular Google search couldn’t handle.
For the sake of no confusion let’s define image search and visual search. Image search is the search for an image using text or words as query whereas visual search (VS) is finding images using images as input query. The results depend on the searched image, its contents, such as metadata, objects, patterns, distribution of color, shape, etc.
Although visual search has immense number of applications in various sectors, it has a direct relationship with fashion and lifestyle industry where products are difficult to put into words and VS comes handy. Almost all the big brands in online and offline-to-online retail have realized the potential of visual search and incorporated it in their shopping platform. A few of these retail giants being Macy’s , Ikea, Tommy Hilfiger, JCpenney, Target , Forever 21 , ASOS etc. By 2021, early adopter brands that redesign their websites to support visual and voice search will increase digital commerce revenue by 30% -Gartner.
VS has come along significant changes on its path of what we see and experience today. A lot of companies have been developing their own VS engines over the years and hence contributing to the technology as a whole.
