Cosine similarity | "Cosine distance" is a term often used for the complement in positive space, that is: formula_1 where formula_2 is the cosine distance and formula_3 is the cosine similarity. It is important to note, however, that this is not a proper distance metric as it does not have the triangle inequality property—or, more formally, the Schwarz inequality—and it violates the coincidence axiom; to repair the triangle inequality property while maintaining the same ordering, it is necessary to convert to angular distance (see below.) |
Cosine similarity | The cosine of two non-zero vectors can be derived by using the Euclidean dot product formula: |
Cosine similarity | Given two vectors of attributes, "A" and "B", the cosine similarity, "cos(θ)", is represented using a dot product and magnitude as |
Cosine similarity | This coefficient is also known in biology as Ochiai coefficient, or Ochiai-Barkman coefficient, or Otsuka-Ochiai coefficient: |
Structural similarity | The SSIM index satisfies the condition of symmetry: formula_21 |
Structural similarity | SSIM is then a weighted combination of those comparative measures: |
Structural similarity | In order to evaluate the image quality, this formula is usually applied only on luma, although it may also be applied on color (e.g., RGB) values or chromatic (e.g. YCbCr) values. The resultant SSIM index is a decimal value between -1 and 1, and value 1 is only reachable in the case of two identical sets of data. Typically it is calculated on window sizes of 8×8. The window can be displaced pixel-by-pixel on the image, but the authors propose to use only a subgroup of the possible windows to reduce the complexity of the calculation. |
Structural similarity | A more advanced form of SSIM, called Multiscale SSIM is conducted over multiple scales through a process of multiple stages of sub-sampling, reminiscent of multiscale processing in the early vision system. The performance of both SSIM and Multiscale SSIM is very high in regards to correlations to human judgments, as measured on widely used public image quality databases, including the LIVE Image Quality Database and the TID Database. Most competitive image quality models are some form or variation of the SSIM concept. |
Structural similarity | Owing to its performance and low computation cost, SSIM has become widely used in the broadcast, cable and satellite television industries. It has become a dominant method of measuring video quality in broadcast and post-production houses throughout the television industry. These achievements were the basis for the team's Emmy Award. |
