FIG. 2D is a block diagram of aserver 205 operating in accordance with an example embodiment of the invention. In an example embodiment, aserver 205 comprises aprocessor 202 and/or media 210. - In an example embodiment, the media 210 comprises one or more quality parameters 220 a-n. For example, the media 210 comprises at least one of the following quality parameters:

Media 210 may also comprise other quality parameters. - In an example embodiment,
resolution 220 a represents a number of pixels for the media 210. In this example embodiment, aresolution 220 a has a pixel count of less than 204800, e.g., 640×320 resolution, may be considered low. In an embodiment,resolution 220 a is identified as a physical size, e.g. lines per millimeter, lines per inch, and/or the like, pixels, an overall size of the media 210, e.g., lines per picture height, and/or the like. In an example embodiment, a resolution of ten lines per millimeter comprises five dark lines alternating with five light lines. - In an example embodiment,
sharpness 220 b determines the clarity of the media 210.Sharpness 220 b of the media 210 may be determined based at least in part on theresolution 220 a and an acutance of the media 210. In an embodiment, the acutance comprises a speed that the media 210 information transitions at an edge or the like. The combination ofresolution 220 a, e.g., clarity, and the acutance, e.g., speed of transition,sharpness 220 b results in thesharpness 220 b of the media 210. In an example embodiment, thesharpness 220 b has a value from 0.0, e.g., low sharpness, to 1.0, e.g., good sharpness. For example, thesharpness 220 b may have aresolution 220 a for a five megapixel image in one megapixel, e.g., 0.2 sharpness. A sharpness of less than 0.5 may be considered low. It should be understood that sharpness may be affected by a lens and/or sensor of a device capturing the media 210, a camera shake, a focus accuracy, an atmospheric disturbance, e.g., thermal effects, aerosols, and/or the like, and/or the like. - In an embodiment, signal-to-
noise ratio 220 c is a variation of image density in a media 210. In an example embodiment, the signal-to-noise ratio 220 c is described in decibels (dB) or effective number of bits (ENOB). If the ENOB is 8 or more, e.g., approx 48 dB, the quality is good. If the ENOB is less than 4, e.g., 24 dB, the signal-to-noise ratio 220 c is low. - In an example embodiment,
dynamic range 220 d is a luminance value comprising a range of light levels theserver 205 may capture for the media 210. The luminance value may be measured in f-stops, exposure value, zones, and/or the like. In an example embodiment, thedynamic range 220 d comprises a minimum and a maximum 8-bit luminance value with thedynamic range 220 d between 0 and 255. A media 210 with a value for thedynamic range 220 d of above 150 is good. - In an example embodiment, a quality parameter is a vertical alignment. The vertical alignment may be an arrangement or position in a straight line, a parallel line, and/or the like, in a position perpendicular to the plane of a horizon. In an alternative embodiment, a quality parameter is a horizontal alignment. The horizontal alignment may be an arrangement in a straight line, a parallel line, and/or the like in a position perpendicular to a plane of the horizon.
- In an embodiment, a quality parameter is facial detection. For example, the quality parameter may indicate if a face is happy, sad, neutral, and/or the like. Further, the quality parameter may indicate other attributes of a face, such as open eyes.
- It should be understood that the
processor 202 may use techniques known in the art for determining the value for each quality parameter 220 a-n. It should be further understood that the value for each quality parameter 220 a-n representing a good, average, low, and/or the like value may be varied based at least in part on the use of the media 210. It should also be understood that embodiments of the invention performed with a video may apply the quality parameters for each frame of a video. - In an example embodiment, the
processor 202 is configured to determine at least one quality parameter for the media 210 on theserver 205 associated with the search request. For example, theprocessor 202 may determine theresolution 220 a, thesharpness 220 b, the signal-to-noise ratio 220 c, thedynamic range 220 d, and/or the like for the media 210. Theprocessor 202 may be configured to assign a value, e.g., representing a good or a low quality, for each quality parameter 220 a-n of the media 210. For example, theprocessor 202 may assign a low numerical value representing alow resolution 220 a for the media 210. In an embodiment, theprocessor 202 is further configured to apply a weight to the value of each quality parameter. - In an example embodiment, the
processor 202 is also configured to calculate a quality score for the media 210 based at least in part on each value for each of the quality parameters 220 a-n. - In an embodiment, the
processor 202 is further configured to apply a weight to the value of each quality parameter. Theprocessor 202 may also be configured to combine the weighted value of each quality parameter using a combination technique, such as addition, multiplication, or using fuzzy logic. For example, theprocessor 202 may add the weighted value for each quality parameter 220 a-n to calculate the quality score. Alternatively, theprocessor 202 may multiply the weighted value for each quality parameter 220 a-n to calculate the quality score. - In an alternative embodiment, each quality parameter 220 a-n is processed with a nonlinear function having a knee point, e.g., threshold value for a good quality score. In an embodiment, the knee point may be a pre-determined value or set by the user representing good quality. If desirable, the
processor 202 may be configured to apply a piecewise linear function, a transcendental function, an algebraic function, fuzzy logic, and/or the like, to determine a quality score for the media 210. In an embodiment, the transcendental function is a logarithm function, an exponential function, and/or the like. In an embodiment, the algebraic linear function is a polynomial function. - In an example embodiment, a piecewise linear function is f: Ω→V, where V is a vector space and Ω may be subset of a vector space. The piecewise linear function may be any function with the property that Ω can be decomposed into finitely many polytopes, such that f is equal to a linear function on each of these polytopes. Embodiments of the invention use the piecewise linear function as known in the art to generate a nonlinearized representation of the quality parameters 220 a-n. Based at least in part on the nonlinearized representation, the
processor 202 may calculate the quality score. - In an alternative embodiment, the
processor 202 is configured to compare one or more quality parameters of the media 210 to one or more quality parameters of a reference media. In an embodiment, the reference media is a known good representation of the media 210. For example, theprocessor 202 may determine a difference in value for each quality parameter of the media 210 and the reference media. Theprocessor 202 may be configured to calculate a quality score based at least in part on the comparison between the media 210 and the reference media. For example, theprocessor 202 may add the difference in value to calculate a quality score. Theprocessor 202 may determine any value less than, for example, a pre-defined amount is of low quality. - In an embodiment, the
processor 202 is also be configured to rank the media 210 based at least in part on the keyword, quality score, or the like. In an embodiment, theprocessor 202 is configured to sort the media based at least in part on a ranking. Further, theprocessor 202 may be configured to sort the media based at least in part on the quality score. In an embodiment, theprocessor 202 is configured to store the quality score in a database. In an embodiment, a database is a collection of data organized for convenient access. In an example embodiment, theprocessor 202 is further configured to access the quality score during a subsequent search instead of calculating a new quality score. - In an example embodiment, the
processor 202 is configured to receive a search request from a client, such asclient 248 ofFIG. 2B . In an example, theprocessor 202 of theserver 205 may use a search engine to examine an index to provide a listing of best-matching media based at least in part on the search research request. If desired, the search engine may rank the media to provide the best results based at least in part on the search criteria. For example, the search engine may provide the best quality media for the keyword entered in theinput box 255. In an example embodiment, theprocessor 202 is also configured to transmit search results based at least in part on the quality score of the media. - In an example embodiment,
server 205 is similar toserver 100,processor 202 is similar to processor 20, anduser interface 250 is similar to display 28. In an alternative embodiment,server 205, processor 215, anduser interface 250 is different thanserver 100, processor 20, and display 28. -

At 330, a quality scored based at least in part on the comparison is calculated. In an example embodiment, the processor calculates a quality score based at least in part on the different in value for each quality parameter of the image as compared to a known good image.
- At 335, it is determined whether there is another media to be processed. If at 335 it is determined that there is another media is to be processed, then the example method continues at 305. If at 335 it is determined that there is not another media to be processed, then the
example method 300 ends. - If it is determined at 320 that there is no reference media, then at 340, a quality score is calculated. In an example embodiment, the processor calculates a quality score based at least in part on one or more quality parameters. At 347, the quality score is stored. In an example embodiment, the processor stores the quality in a database.
