1. A system for detecting text in images, the system comprising:
a database, wherein the database is configured to store images, candidate characters in the images, and a color associated with the candidate characters;
an image capture device, wherein the image capture device is configured to capture images of products, and
a control circuit coupled to the image capture device and the database, the control circuit configured to:
receive an image of a product captured by the image capture device;
detect characters on the product in the image;
detect a color associated with the characters on the product in the image;
recognize the characters on the product in the image;
recognize the color associated with the characters on the product in the image;
determine, based on accessing the database, a logo including the candidate characters on one of the products in one of the stored images;
determine, based on accessing the database, a color associated with the logo; and
verify the recognition of the characters on the product in the image based on a matching of the color associated with the characters on the product in the image and the color associated with the logo.
