Convert a color image between color representations.

B = COLORSPACE(S,A) converts the color representation of image A

where S is a string specifying the conversion. S tells the

source and destination color spaces, S = dest<-src , or

alternatively, S = src->dest . Supported color spaces are



RGB R G B Red Green Blue (ITU-R BT.709 gamma-corrected)

YPbPr Luma (ITU-R BT.601) + Chroma

YCbCr / YCC Luma + Chroma ("digitized" version of Y PbPr)

YUV NTSC PAL Y UV Luma + Chroma

YIQ NTSC Y IQ Luma + Chroma

YDbDr SECAM Y DbDr Luma + Chroma

JPEGYCbCr JPEG-Y CbCr Luma + Chroma

HSV / HSB Hue Saturation Value/Brightness

HSL / HLS / HSI Hue Saturation Luminance/Intensity
