Abstract: Various approaches provide for detecting and recognizing text to enable a user to perform various functions or tasks. For example, a user could point a camera at an object with text, in order to capture an image of that object. The camera can be integrated with a portable computing device that is capable of taking the image and processing the image (or providing the image for processing) to recognize, identify, and/or isolate the text in order to send the image of the object as well as recognized text to an application, function, or system, such as an electronic marketplace.

Abstract: Various embodiments provide a method for computing color descriptors of product images. For example, a number of fine color representatives can be determined to describe color variation in an image as a histogram by assigning a saturation value and a brightness value to a plurality of color hues. For each pixel of the image, the closest color among a defined fine color representative set is computed. In this example, each of the pixels is assigned a color ID corresponding to their closest matching fine color representative and at least one family color ID corresponding one or more pure color families. In this example, a histogram of the color representatives and a histogram for the color families are computed. A single color vector descriptor for the image is then determined by combining the family histogram with the color representative histogram.

Abstract translation: 各种实施例提供了一种用于计算产品图像的颜色描述符的方法。 例如，通过将饱和度值和亮度值分配给多个色调，可以确定许多细色代表以描述图像中的颜色变化作为直方图。 对于图像的每个像素，计算定义的精细颜色代表集合中最接近的颜色。 在该示例中，为每个像素分配与其最接近的匹配细色代表相对应的颜色ID和对应于一个或多个纯色族的至少一个族色ID。 在该示例中，计算颜色代表的直方图和颜色族的直方图。 然后通过将族直方图与颜色代表性直方图组合来确定用于图像的单个颜色矢量描述符。
