摘要： Embodiments of a processing systems and methods can unbend an image of facing pages of a bound book. An exemplary processing system can comprise an edge-detection unit, a keystone-correction unit, a flattening unit, and a conversion unit. After an image is received by the processing system, the image can be processed in turn by each unit. The edge-detection unit can identify edges of a document in the image. The keystone-correction unit can reduce or remove keystoning in the image, thereby correcting horizontal distortion of the document. The flattening unit can flatten or straighten text or objects in the image, thereby correcting vertical distortion of the document. The conversion unit can convert the image to a desired color profile. Accordingly, the processing system can process an original image into a more easily readable and digitally manipulable image.
摘要翻译：处理系统和方法的实施例可以解除绑定书的面对页面的图像。示例性处理系统可以包括边缘检测单元，梯形失真校正单元，平坦化单元和转换单元。在处理系统接收到图像之后，可以依次由每个单元处理图像。边缘检测单元可以识别图像中文档的边缘。梯形失真校正单元可以减少或消除图像中的梯形失真，从而校正文档的水平失真。平整单元可以使图像中的文本或对象变平或变直，从而校正文档的垂直变形。转换单元可以将图像转换为所需的颜色特征。因此，处理系统可以将原始图像处理成更容易读取和数字可操纵的图像。

An exemplary processing system can comprise an edge-detection unit, a keystone-correction unit, a flattening unit, and a conversion unit. After an image is received by the processing system, the image can be processed in turn by each unit: The edge-detection unit can identify edges of a document in the image. The keystone-correction unit can reduce or remove keys toning in the image, thereby correcting horizontal distortion of the document. The flattening unit can flatten or straighten text or objects in the image, thereby correcting vertical distortion of the document. The conversion unit can convert the image to a desired color profile. Accordingly, the processing system can process an original image into a more easily readable and digitally manipulate image.

摘要： An electronic whiteboard system with an eraser device is disclosed. The electronic whiteboard system can comprise a writing surface and a retro-reflective perimeter. One of more optical detection elements can be disposed at the corners of the perimeter. The detection elements can emit a light beam and detect its reflection. The system can detect the presence of an object in proximity to the writing surface by the absence of reflected light. The erasing device can comprise retro-reflective elements. The retro-reflective elements can produce a distinct reflective pattern observed by the detection elements when they reflect the emitted light beams. The reflective pattern can be analyzed to determine the orientation of the erasing device relative to the writing surface. By determining the actual orientation of the erasing device ghosting, or ambiguity in the orientation of device, can be eliminated or substantially reduced.
摘要翻译：公开了一种具有橡皮擦装置的电子白板系统。电子白板系统可以包括书写表面和反光外围。更多的光学检测元件之一可以设置在周边的角部。检测元件可以发射光束并检测其反射。该系统可以通过不存在反射光来检测靠近书写表面的物体的存在。擦除装置可以包括回射元件。当反射元件反射发射的光束时，回射元件可以产生由检测元件观察到的不同的反射图案。可以分析反射图案以确定擦除装置相对于书写表面的取向。通过确定擦除装置重影的实际取向，或者可以消除或显着减少装置取向的模糊性。
