Abstract:
A method for detecting an image corresponding to at least a monetary banknote is provided. The method includes selecting a detection procedure from a plurality of different detection procedures, and verifying the image according to the selected detection procedure.
Abstract:
An image processing system with ambient sensing capability includes an image sensing device and an ambient sensing device. The image sensing device is used for sensing a scene to generate original image data. The ambient sensing device is coupled to the image sensing device, for analyzing a part of the original image data to generate an ambient sensing result.
Abstract:
A method for generating a non-graphical digital image from an original digital image includes the following steps: performing edge detection to generate a third digital image, performing screen dot detection to detect the photo regions in the original digital image, detecting color regions in the original digital image, removing the photo regions and the color regions from the third digital image to generate the non-graphical digital image.
Abstract:
A protection method for preventing a hard copy of a document from being released or reproduced is provided. The protection method comprises: selecting a pattern with a closed contour line and utilizing a level set method to process the pattern to generate at least a watermark; and embedding the watermark into the document. In addition, the protection method can further comprise: detecting the hard copy of the document to determine whether at least a watermark exists in the hard copy of the document; and forbidding releasing or reproducing the document when the watermark is detected in the hard copy of the document.
Abstract:
A color processing method for identification of areas within an image corresponding to monetary banknotes includes dividing the image into a plurality of sections; extracting color histogram data for each section; assigning a color vector for each section according to the color histogram data for the section; comparing the color vector for each section to a color lookup table to determine a probability of the section corresponding to monetary banknotes; and selecting probable sections having the probability exceeding a first predetermined threshold.
Abstract:
A notebook computer with a multi-image capturing function is provided. The notebook computer includes an image pickup device and a mirror. The image pickup device is used for capturing a first image. The mirror is disposed beside the image pickup device and tilted by an angle with respect to the image pickup device. A second image reflected by the mirror is adjustable by changing the angle. The second image reflected by the mirror is also captured by the image pickup device, so that the first image and the second image are simultaneously captured by the image pickup device.
Abstract:
An image pickup system includes a base, a frame, an image pickup device, a receiving structure, a marking element and a switching element. The frame is connected to the base. The image pickup device is disposed on the frame. The receiving structure is disposed in the base. The frame is rotatable with respect to the base, so that the image pickup device is moved to an optimal shooting position. The marking element indicates that the image pickup device is at the optimal shooting position. When the switching element is triggered, the target object placed in the receiving structure will be shot by the image pickup device.
Abstract:
An image brightness adjusting method is provided. The brightness values of all pixels of the image are firstly increased in various increasing degrees. Next, the increased brightness values are decreased in various decreasing degrees according to the original brightness values, thereby avoiding over-increasing the brightness values of the image. Moreover, the use of the color saturation values to adjust the brightness values can avoid the unnatural image appearance.
Abstract:
A method for detecting a boundary of a monetary banknote within an image includes dividing the image into a plurality of sections; generating a color feature map containing color histogram data for each section of the image; generating a gray level feature map indicating a gray level value for each section of the image; recording border sections onto a banknote boundary map, the border sections being sections having color histogram data within a first predetermined range and gray level values within a second predetermined range; removing internal border sections enclosed by perimeter border sections from the banknote boundary map; and dilating the perimeter border sections on the banknote boundary map.
