  • Patent number: 10049308
    Abstract: Training images can be synthesized in order to obtain enough data to train a convolutional neural network to recognize various classes of a type of item. Images can be synthesized by blending images of items labeled using those classes into selected background images. Catalog images can represent items against a solid background, which can be identified using connected components or other such approaches. Removing the background using such approaches can result in edge artifacts proximate the item region. To improve the results, one or more operations are performed, such as a morphological erosion operation followed by an opening operation. The isolated item portion then can be blended into a randomly selected background region in order to generate a synthesized training image. The training images can be used with real world images to train the neural network.

    Abstract: Techniques for using multiple modulation schemes for a single packet are described. Each data packet is processed and transmitted in up to T blocks, where T>1. Multiple modulation schemes are used for the T blocks to achieve good performance. A transmitter encodes a data packet to generate code bits. The transmitter then forms a block of code bits with the code bits generated for the packet, determines the modulation scheme to use for the block (e.g., based on a mode/rate selected for the packet), maps the code bits for the block based on the modulation scheme to obtain data symbols, and processes and transmits the block of data symbols to a receiver. The transmitter generates and transmits another block in similar manner until the data packet is decoded correctly or all T blocks have been transmitted. The receiver performs the complementary processing to receive and decode the packet.

  • Patent number: 9076703
    Abstract: An actuator is configured to move a sensor array between first and second positions in order to provide color image data and other data with full resolution of the sensor array. In many embodiments, the output resolution of the sensor array for each type of data comprises twice the resolution of the sensor array without movement. The alternating movement of the sensor array between the first and second positions provides output images with decreased artifacts that might otherwise be present without the alternating movement of the sensor array.

  • Patent number: 9066051
    Abstract: A method and a device are disclosed for luminous printing of an original image using fluorescent ink or other fluorescent display pigments. In some embodiments, the original image is separated into multiple layers, including at least a brightness layer and an inverse brightness (or darkness) layer, by applying extracted brightness data and inverse brightness data, to the original image, respectively. Each of the layers is associated with a set of corresponding printing channels. The sets of printing channels are applied by a printing device to print the original image on a print medium, such as paper, mylar, fabric, and other print surfaces. Multiple visual effects may be realized using the aforementioned process, including fluorescent images that are only visible under UV (Ultra Violet) or black light, images with high-fidelity colors under daylight and dark conditions, and shadow effects such as depth illusion.

  • Patent number: 9049403
    Abstract: An embodiment implements a methodology for printing non-saturated text and lines in a way that removes the jagged edge problem. An embodiment uses a combination of two screens, e.g. AM screening and applying pure color. For example, according to the embodiment, the closer to the edge from the interior of text or lines, the less amplitude modulation half toning is applied and the more actual color or contone is applied. A particular algorithm for determining and using a blending parameter is provided.

  • Patent number: 9013771
    Abstract: A color conversion method, medium, and apparatus, converting a color temperature of an image to a user-set color temperature, on a pixel-by-pixel basis, based on the brightness of each pixel of the image. The color temperature conversion method may include determining a first information associated with a conversion range, determining whether the color temperature of the input pixel needs to be converted by determining, based on the first information, whether the input pixel is within the conversion range, calculating color coordinates of a target point if the input pixel is within the conversion range, and converting the color temperature of the input pixel by moving, in the same direction as the reference point to the target point an amount proportional to the reference point displacement so that the input pixel can be automatically moved along with the reference point of the conversion range.

  • Patent number: 9001346
    Abstract: A signal processing circuit includes a generator, a transmission unit, a control unit, and a mode selector. The generator generates a process-required signal. The transmission unit transmits the process-required signal to a unit disposed after the transmission unit. The control unit supplies respective control signal to the generator and transmission unit. The control unit includes a reference clock generator constantly operated for generating a reference clock signal when the signal processing circuit is operated. The mode selector selects and shifts an operating mode of the signal processing circuit between a first mode and a second mode. In the first mode, the generator and transmission unit are supplied with respective normal control signal from the control unit for a normal operation. In the second mode, the generator is supplied with a control signal different from the normal control signal, and the transmission unit is supplied with the same normal control signal.

  • Patent number: 8982417
    Abstract: An image processing apparatus includes a color conversion processing unit, a modulation difference creating unit, a color value modulating unit, and an output unit. The color conversion processing unit performs color conversion from an input color value of a target image to a corresponding output color value to obtain a tentative output color value. The modulation difference creating unit creates modulation differences. The modulation differences include combinations that are obtained by either setting or not setting a value equivalent to the minimum resolution of the tentative output color value for each color component of the tentative output color value. The color value modulating unit performs modulation on the tentative output color value by adding or subtracting a modulation difference selected at random to or from the tentative output color value. The output unit outputs the target image according to the color value obtained after modulation.
