摘要:
The prevented invention provides a method to visualize complicated metro maps in a limited displaying area, in which the route to the passenger's destination is highlighted. In order to achieve high readability, it sets 1) the distance between neighboring stations to be equal, 2) the transportation lines to lie in octilinear directions, 3) the angles of incident edges at each station to be maximized, and 4) the station positions to be inside the displaying area. It also labels the names of stations that passenger will pass by to make the route navigation easy and intuitive.

A reframing application crops a sub-part of a video source, based on its content. The reframing application involves a visual attention model that produces a saliency map, and a dedicated reframing algorithm that extrapolates a cropping window based on that saliency map. After cropping, only the reframed portion of each video image remains visible. A method for processing images of a video sequence comprises steps of determining parameters of the video sequence, parameters of a previously decoded subsequence of the video sequence and user settings, determining a portion to be cropped according to the determined parameters, and cropping in a reframing step the determined portion for being displayed. An advantage of the invention is that an advanced automatic solution is provided for tuning automatically the reframing parameters, based on the content of a video.

A system, method, and computer program product are provided for generating an image thumbnail. In operation, an image is received. Additionally, a most relevant portion of the image is determined. Further, a cropping area is identified, based on the most relevant portion of the image. The cropping area is applied to the image. Moreover, an image thumbnail for the image is generated, based on the applied cropping area.

In some instances, an image may have dimensions that do not correspond to a slot to display the image. For example, an image content item may have dimensions that do not correspond to a content item slot. The image may be resized using seam carving to add or remove pixels of the image. A saliency map for the image may be used having saliency scores for each pixel of the image. Evaluation metrics may be used before, during, and after, seam carving to determine whether salient content is affected by the seam carving. In some instances, a seam cost threshold value may be used for adaptive step size during the seam carving. The resized image may then be outputted, such as for an image content item to be served with a resource.

Provided is an image processing apparatus, including an enlargement ratio setting section which sets a region of data in an original image, including a designated position designated as an object to be enlarged within the original image, as a region to be enlarged, and sets an enlargement ratio to the region to be enlarged, based on an image feature amount showing complexity of an image of the region to be enlarged, and an enlarged image generation section which generates enlarged image data for the data of the original image, by applying an enlargement process by the enlargement ratio set by the enlargement ratio setting section.

Systems and methods are provided for improving the visual quality of low-resolution video displayed on large-screen displays. A video format converter may be used to process a low-resolution video signal from a media providing device before the video is displayed. The video format converter may detect the true resolution of the video and deinterlace the video signal accordingly. For low-resolution videos that are also low in quality, the video format converter may reduce compression artifacts and apply techniques to enhance the appearance of the video.
摘要:
The subject matter of this specification can be embodied in, among other things, a method that includes receiving an image having indication pixels that define a plurality of regions within the image that are used for resizing the image and determining, based on the indication pixels, two or more of the regions that are stretchable regions that change size when the image is resized. The method also includes resizing the image by changing a size of at least one of the determined stretchable regions.
摘要:
A method of performing an image retargeting quality assessment comprising comparing an original image and a retargeted image in a frequency domain, wherein the retargeted image is obtained by performing a retargeting algorithm on the original image. The disclosure also includes an apparatus comprising a processor configured to perform an image retargeting quality assessment, and compare an original image and a retargeted image in a spatial domain, wherein the retargeted image is obtained by performing a retargeting algorithm on the original image, and wherein comparing the original image and the retargeted image in the spatial domain comprises comparing the original image and the retargeted image to determine an amount of shape distortion between the images.
摘要:
A method, apparatus and computer program where the method comprises determining a plurality of areas of interest where the areas are isolated from each other by intermediate areas; and non-uniformly scaling a map comprising the plurality of areas of interest by changing the relative scaling between the plurality of areas of interest and the intermediate areas.
摘要:
Systems and methods for creating and editing seam carving masks may allow a user to combine masks, and/or to modify automatically generated suggested masks, manually created masks, combination masks, or previously stored masks using tools of a graphical user interface in a graphics application (e.g., a mask brush or mask eraser). The method may include accessing data representing an image and automatically generating a suggested mask for the image (e.g., based on a color or color range, a threshold energy value, or input specifying two or more previously stored masks for combination). The method may include displaying the suggested mask as an overlay of the image, highlighting mask pixels using a respective color or pattern. The user may indicate pixels to be added to or removed from the suggested mask to produce a modified mask for application in an image editing operation (e.g., a resizing, filtering, or feature identification operation).
