Creative Marketing

Everyone must remember how fun it was to play hide and seek when you were a kid. This actually reveals a common property of human beings: like to discover and surprise. With our image matching API, you can easily create a smart phone App to take a photo shot of LOGO, posters, or any model item, and then use image matching for a creative marketing experience.See Demo

Fabric Search and Matching

Fabric search and matching is different from generic similarity visual search in two aspects. One is that a user can take pictures of arbitrary rotation of a fabric thus generating different images. Another one is that it will create different images by zooming in or out. In both cases, users expect to be able find the items by visual search. We have created a special search engine specifically for the textile industry,thus making fabric visual search a reality.
