摘要:
Reducing or eliminated color-dependent vignetting in a digital camera includes: providing, for each color that said camera can image, a raw array of data corresponding to a desired scene; and changing the raw arrays such that the array for each color exhibits substantially the same amount of vignetting so as to reduce color-dependent vignetting in a composite image based upon each of the changed arrays.
摘要:
Disclosed are systems and methods for providing spatially-varied demosaicing. In one embodiment, a system and method pertain to collecting color information sensed by image sensor pixels, and estimating color information as to a pixel under consideration that is not collected by the pixel by weighting color information collected by adjacent pixels that are positioned in a direction in which color is shifted due to lateral chromatic aberration.
摘要:
A method of local contrast mapping that changes the dynamic range of an original image to more closely match the dynamic range of the medium used for the reproduction. The method compresses large contrast differences between different areas of an image while preserving small contrast differences between different areas of an image.
摘要:
A system and method for modifying the sensitivity of various image-editing parameters in accordance with the result obtained from one or more visual-acuity tests are disclosed. The method generally includes the steps of: identifying a new operator of the image-processing system; presenting a visual-acuity test to the operator via an interface to identify a control parameter sensitivity value associated with the operator's visual acuity limit; and adjusting the control parameter sensitivity value accordingly. The method may be implemented by an image-processing system having an image acquisition device, a processor, a memory device, a user-input device, and a display.
摘要:
The present disclosure relates to systems and methods for customizing a software application interface. A method for modifying a software application contains the following steps: identifying the operator; acquiring an operator profile; setting a threshold value; monitoring the operator's use of the software; and modifying a functional interface when the threshold is exceeded.
摘要:
An automatic level-sensitive Laplacian filter for image processing. Laplacian filter coefficients and normalization divisors are made a function of intensity on a pixel by pixel basis. Pixels indicating a high intensity may be greatly changed by neighboring pixels. Pixels indicating a low intensity receive relatively little or no filtering. In a specific example embodiment, the intensity range is divided into bands, with a different filter for each band. The resulting images are visually sharpened (edge enhanced) with very little impact in darker areas of the image.
摘要:
A novel method of tumor immunotherapy is described comprising the genetic modification of cells resulting in the secretion of cytokine gene products to stimulate a patient's immune response to tumor antigens. In one embodiment, autologous fibroblasts genetically modified to secrete at least one cytokine gene product are utilized to immunize the patient in a formulation with tumor antigens at a site other than an active tumor site. In another embodiment, cells genetically modified to express at least one tumor antigen gene product and to secrete at least one cytokine gene product are utilized in a formulation to immunize the patient at a site other than an active tumor site.
摘要:
An electronic image capture device including an image capture array, an optional image stabilization gyro, a processor, and a display is configured to detect the amount shaking of the device either prior to, or during image capture. When the shaking of the device exceeds a threshold required for the capture of quality images, the user of the image capture device is notified through the display that excessive shake has been detected and may be advised on methods to reduce or eliminate the shake.
摘要:
A digital imaging device detects or tracks a user's direction of gaze. The detected direction of gaze may be used to set one or more functions in the digital imaging device, and the history of the user's direction of gaze may be stored with a captured digital image for later use by an automatic image post-processing apparatus.
摘要:
The invention provides a method of preventing or reducing the severity of a cancer in a subject by stimulating the subject's immune response against the cancer. The invention provides, for example, a method of stimulating an immune response in a subject by administering to the subject tumor cells that are substantially similar to the subject's cancer cells and that are genetically modified to reduce or inhibit the expression of one or more immunosuppressive agents. The invention also provides a method of preventing or reducing the severity of cancer in a subject by stimulating the subject's immune response against the cancer by administering to the subject tumor cells that are substantially similar to the subject's cancer cells and that are genetically modified to prevent the expression of an immunosuppressive agents and, in combination with the genetically modified tumor cells, an immunostimulatory agent. The invention further provides compositions useful for practicing the claimed methods.
