摘要： Methods and systems for denoising and artifact removal in image upscaling are disclosed. In one embodiment, a low frequency band image intermediate is obtained from an input image. An upsampled image intermediate is obtained from the input image by upsampling. A result image is estimated, based at least in part on the upsampled image intermediate, the low frequency band image intermediate, and the input image. The input image is of a smaller scale than the result image. The estimating the result image further includes eliminating from the result image noise that is present in the input image.

摘要： Methods, apparatus, and computer-readable storage media for tone mapping High Dynamic Range (HDR) images. An input HDR image is separated into luminance and color. Luminance is processed to obtain a base layer and a detail layer. The base layer is compressed according to a non-linear remapping function to reduce the dynamic range, and the detail layer is adjusted. The layers are combined to generate output luminance, and the output luminance and color are combined to generate an output image. A base layer compression technique may be used that analyzes the details and compresses the base layer accordingly to provide space at the top of the intensity scale where the details are displayed to thus generate output images that are visually better than images generated using conventional techniques. User interface elements may be provided via which a user may control one or more parameters of the tone mapping method.

摘要： Methods and apparatus for soft edge masking. A soft edge masking technique may be provided via which, starting from an initial, potentially very rough and approximate border selection mask, the user may selectively apply brush strokes to areas of an image to selectively improve the border region of the mask, thus providing softness details in border regions which contain soft objects such as hair and fur. A stroke may be an additive stroke indicating a particular region in which detail from an original image is to be added to a composite image, or a subtractive stroke indicating a particular region in which detail is to be removed from the composite image. The stroke may also indicate a strength parameter value that may be used to indicate an amount of bias to be used in opacity calculations for the affected pixels.

摘要： A system and method for expansion and reduction of images uses a hybrid resizing technique combining seam carving and image scaling techniques to reduce or expand an input image. Seam carving techniques may be used to remove or add seams of the image to perform a portion of an overall resizing operation, according to a configurable seam carving tolerance. For example, the technique may only remove and/or replicate a predetermined number or percentage of the lowest-cost seams of the image, or may only remove or replicate the number of low-cost seams needed to achieve a specified percentage of the target resizing operation. The hybrid technique may apply scaling techniques to further resize the image to achieve a target size and/or ratio for the resized image. The hybrid technique may be implemented by program instructions of an image editing application, and the seam carving tolerance may be configurable by a user.

摘要： A system and method for expansion and reduction of images uses a hybrid resizing technique that combines seam carving and image scaling techniques to reduce or expand an image. Seam carving techniques may be used to remove or add seams having an average or total energy cost below a configurable threshold, where the cost of each seam is dependent on the energy values of the pixels of the seam. If a target size and/or ratio for the resized version of the image is not reached by removing or adding these seams, the hybrid resizing technique may apply standard or custom image scaling techniques to further reduce or expand the image to achieve the target size and/or ratio. The hybrid technique may be implemented by program instructions of an image editing application, and the cost threshold may be configurable by a user through a user interface of the image editing application.

摘要： A system and method for expansion and reduction of images in an image editing application uses the frequency of pixels values (e.g., absolute color and/or intensity values) of an input image to determine respective energy values for each pixel of the image. The energy values may vary inversely with the frequency of the pixel values. The energy values may be used to determine one or more low-cost seams of the image to be removed for an image reduction operation or replicated for an image expansion operation, where the cost of each seam is dependent on the energy values of the pixels of the seam. Determining the frequency of pixel values of the image may involve determining the number of pixels having an absolute pixel value in each of a plurality of pixel value ranges, and the absolute pixel values included in each range may be configurable by the user.
