    Abstract: A computer peripheral that may operate as a scanner. The scanner captures image frames as it is moved across an object. The image frames are formed into a composite image based on computations in two processes. In a first process, fast track processing determines a coarse position of each of the image frames based on a relative position between each successive image frame and a respective preceding image determine by matching overlapping portions of the image frames. In a second process, fine position adjustments are computed to reduce inconsistencies from determining positions of image frames based on relative positions to multiple prior image frames. The peripheral may also act as a mouse and may be configured with one or more navigation sensors that can be used to reduce processing time required to match a successive image frame to a preceding image frame.

    Abstract: A method of scanning an image of a document with a portable electronic device includes interactively indicating in substantially real time on a user interface of the portable electronic device, an instruction for capturing at least one portion of an image to enhance quality. The indication is in response to identifying degradation associated with the portion(s) of the image. The method also includes capturing the portion(s) of the image with the portable electronic device according to the instruction. The method further includes stitching the captured portion(s) of the image in place of a degraded portion of a reference image corresponding to the document, to create a corrected stitched image of the document.

    Abstract: A plurality of image data obtained by divided-capturing an object and correction image data obtained by capturing a correction chart at an angle of view wider than that in the divided capturing are input. Heterogeneity of luminance in the plurality of image data is corrected based on the correction image data. Joined image data representing the entire image of the object is generated by joining the plurality of image data in which the heterogeneity of luminance has been corrected.

    Abstract: Two images are stitched together through minimization of a cost function that consists of registration errors from image data of the two images, as well as the estimated errors from a set of sensors. The weight function in the cost function is derived from the confidence value of sensor estimation that considers the sensor errors including lift and off page as well as a measure of accuracy of the sensor readings. Weights are used to adjust image registration accuracy against sensor accuracy to produce a set of registration parameters that would best stitch the two images together. In order to handle large errors for initial registration parameters and to avoid local minima in the minimization process, the image pair may be registered in a lower resolution and then refined in a higher resolution.

    Abstract translation: 通过最小化两个图像的图像数据的注册错误的成本函数以及来自一组传感器的估计误差来将两个图像缝合在一起。 成本函数中的权重函数是从传感器估计的置信度值得出的，该估计考虑了包括提升和离页的传感器错误以及传感器读数精度的度量。 重量用于根据传感器精度调整图像配准精度，以产生一组最佳地将两张图像拼接在一起的配准参数。 为了处理初始注册参数的大错误并避免最小化过程中的局部最小值，图像对可以以较低分辨率登记，然后以更高分辨率进行精化。
