    Abstract: A portable computing device reads information embossed on a form factor utilizing a built-in digital camera and determines dissimilarity between each pair of embossed characters to confirm consistency. Techniques comprise capturing an image of a form factor having information embossed thereupon, and detecting embossed characters. The detecting utilizes a gradient image and one or more edge images with a mask corresponding to the regions for which specific information is expected to be found on the form factor. The embossed form factor may be a credit card, and the captured image may comprise an account number and an expiration date embossed upon the credit card. Detecting embossed characters may comprise detecting the account number and the expiration date of the credit card, and/or the detecting may utilize a gradient image and one or more edge images with a mask corresponding to the regions for the account number and expiration date.

    Abstract: Techniques and systems are provided for determining features of one or more objects in one or more images. For example, an image of an object and a three-dimensional model associated with the object can be obtained. From the image, a sample point on the object can be determined. A depth and an angle of the sample point of the object can be determined. A pose and a shape of the three-dimensional model associated with the object can be determined based on the depth and the angle.

    Abstract: Techniques described herein provide a method for automatically and intelligently creating and updating an OCR cache while performing OCR using a computing device. An image captured using a camera coupled to the computing device may be matched against prior images stored in the OCR cache. If a match is found, the OCR cache may be updated with new or better information utilizing the new image. The matched prior image may be retained in the OCR cache, or the new captured image may replace the matched prior image in the OCR cache. In one embodiment, techniques are described to remove or reduce glare before storing the image in the OCR cache. In some embodiments, glare is removed or reduced in the absence of performing OCR.

    Abstract translation: 本文描述的技术提供了一种用于在使用计算设备执行OCR时自动和智能地创建和更新OCR高速缓存的方法。 使用耦合到计算设备的照相机捕获的图像可以与存储在OCR高速缓存中的现有图像相匹配。 如果找到匹配，则可以利用新图像更新新的或更好的信息来OCR缓存。 匹配的先前图像可以保留在OCR高速缓存中，或者新的捕获图像可以替代OCR高速缓存中的匹配的先前图像。 在一个实施例中，描述了在将图像存储在OCR高速缓存中之前去除或减少眩光的技术。 在一些实施例中，在没有执行OCR的情况下，眩光被去除或减少。
