Light sensitivity is caused by a number of conditions that affect the eye (such as iritis, uveitis, and keratitis), as well as conditions that affect the entire body. Migraine headache is a common cause of photophobia, with a majority of migraine sufferers reporting sensitivity to light.
bNewQmatrix. Indicates which new inverse-quantization matrices are present in an inverse-quantization matrix buffer. Each element in this array corresponds to an inverse-quantization matrix type and indicates whether a new inverse-quantization matrix of that type is present in the buffer.he DXVA_QmatrixData structure is sent by the host decoder to the accelerator to load inverse-quantization matrix data for off-host bitstream compressed video picture decoding.
An inverse function is a function that undoes the action of the another function. A function $g$ is the inverse of a function $f$ if whenever $y=f(x)$ then $x=g(y)$.In other words, applying $f$ and then $g$ is the same thing as doing nothing.We can write this in terms of the composition of $f$ and $g$ as $g(f(x))=x$. function $g$ is the inverse of a function $f$ if whenever $y=f(x)$ then $x=g(y)$. In other words, applying $f$ and then $g$ is the same thing as doing nothing.
