This paper proposes a single-precision Floating Point MAC engine to accelerate the sliding window algorithm for the 2-D convolution of ...
WebFloating point type images make it possible to store these new, not-necessarily-integer values in an efficient way. That can be important, because we could lose a lot of information if we always had to round pixel values to integers. Floating point images also allow us to store three special values: + ∞, − ∞ and NaN . WebThere are two common representations for RGB images with an alpha channel: Straight (unassociated) alpha: R, G, and B channels represent the color of the pixel, disregarding its opacity. Premultiplied (associated) alpha: R, G, and B channels represent the color of the pixel, adjusted for its opacity by multiplication.
WebIt supports both floating-point and normalized integer formats, as well as sRGB encoding for normalized integers. It can even compress different channels separately, like RGTC formats. Despite being color formats, compressed images are not color-renderable, for obvious reasons.
