摘要： A system and method for expansion and reduction of images uses an absolute value associated with each pixel of an input image (e.g., a color and/or intensity value) to determine a respective energy value for each pixel. For example, a given color or range of colors (e.g., skin tones, or other high-priority colors) may be assigned higher energy values than other colors and/or color ranges, and may be protected during image reduction and/or expansion. These energy values may be used to determine a cost associated with various seams of the image, which may represent the priority of the seams in the image. One or more low-cost seams may be identified for removal or replication to produce a resized image. The methods may be used in conjunction with an automated skin tone detector or a user interface that allows selection of one or more high priority colors or color ranges.

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.

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 uses a look-up table to define an arbitrary mapping of data (e.g., pixel values) representing an image to respective energy values. Each pixel value may represent an absolute color or intensity value, a difference in color or intensity values, or an average, derivative, minimum, or maximum of two or more pixel values. The energy values may then 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. The look-up table may be used to apply a threshold and/or cap on the energy values mapped to pixel values. The look-up table may also provide a mechanism for reconfiguring mappings, thresholds, and/or caps.

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 identify one or more low-cost seams of an input image, and these low-cost seams may be scaled up or down to expand or reduce the overall input image and produce a resized image. A different scaling factor may be applied to different ones of the low-cost seams, dependent on the average or total energy value of each of the seams. The scaling factor applied to each seam may be dependent on the number of low-cost seams identified for scaling, which may be configurable by a user. A configurable look-up table may map seam costs to scaling factors, and may be accessed to determine a respective scaling factor to be applied to each identified seam.

摘要： A system and method for expansion and reduction of images uses pyramidal retargeting to reduce complexity in image resizing. An image pyramid may be generated dependent on a function of pixel data or energy values for each pixel of an input image. An image resizing solution may be developed by applying seam carving techniques to a lower-resolution version of the input image represented by the image pyramid, and may identify bands in the higher-resolution input image to be resized. A resizing operation may then be applied the bands based on local content. The resizing operation may include seam carving techniques, scaling techniques, and/or hybrid resizing techniques, and may be selectable by a user. Identified bands may be expanded to obtain a smoother solution. Different bands may be expanded by different amounts, based on local content. The number of bands and the expansion factors may be configurable based on user input.

摘要： A system and method for expansion and reduction of images may apply resizing techniques independently to different regions of an input image to produce a resized version of the image having a specified target size and/or ratio. A content-aware resizing technique may be applied to some regions of the image. Each region may be reduced or expanded by the same amount based on local content, or different regions may be resized by different amounts to meet a resizing target for the input image. The same resizing technique may be applied to each region, or different resizing techniques may be applied to different regions. A given region or unselected portion of the image may not be resized at all. The techniques may be implemented by program instructions of an image editing application, and the definition of the regions and/or the selection of locally applied techniques may be configurable by a user.

摘要： A system and method for expansion and reduction of images uses variable seam replication to expand an image. Seam carving techniques may be used to identify one or more low-cost seams of an input image, and these low-cost seams may be replicated to produce a resized version of the image. A different replication factor may be applied to different ones of the low-cost seams, dependent on the average or total energy value of each seam. For example, the lowest cost seam may be replicated twice as many times as the next lowest cost seam. The replication factor applied to each seam may be dependent on the number of low-cost seams identified for replication, which may be configurable by users. A configurable look-up table may map seam costs to replication factors, and may be accessed to determine a respective replication factor to be applied to each of the identified low-cost seams.

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.
