    摘要： Techniques to allow for optimizing an image based on an operational context. An operational context including at least one attribute of a client associated with a user of a social networking system is determined. An optimized image is created based on the operational context for provision to the user. The determining the operational context may comprise receiving a client identifier and determining the at least one attribute of the client based on the client identifier. The determining the operational context may comprise receiving location coordinates and determining quality of a data connection based on the location coordinates. The determining the operational context may comprise determining at least one usage trend in at least one geographic locality. The optimized image is provided to an image repository associated with the at least one geographic locality. The operational context may comprise at least one user-defined setting.

    摘要： Techniques for accurate color representation of images stored within a social networking system. In an embodiment, an error metric and a target error threshold are determined. A binary search algorithm and a simulated annealing algorithm are performed. A color profile for transforming an image in a first color space to a second color space is created based on the binary search algorithm, the simulated annealing algorithm, the error metric, and the target error threshold. Determination of the error metric may comprise determining a frequency with which a color occurs in the image, assigning a weight to the color based on the frequency, and calculating the error metric based on the weight. Determination of the error metric may comprise dividing the image into a plurality of sections, assigning a plurality of importance values to the plurality of sections, and calculating the error metric based on the plurality of importance values.
