Hello,

I am new to this group. I want to convert YUV format to RGB format and vice versa.... in C++. Any specific link or suggestion would be useful...

thanks in advance...

Maybe this helps...

/*================================== RGB-YUV =================================*/
void rgb_to_yuv(float r[8][8],float g[8][8],float b[8][8],float y[8][8],float u[8][8],float v[8][8])
{
int i,j;

for ( i=0 ; i<8 ; i++ ){
for ( j=0 ; j<8 ; j++ ){
y[i][j]= 0.299 *r[i][j]+0.587 *g[i][j]+0.114 *b[i][j] ;
u[i][j]=-0.1687*r[i][j]-0.3313*g[i][j]+0.5 *b[i][j]+128;
v[i][j]= 0.5 *r[i][j]-0.4187*g[i][j]-0.0813*b[i][j]+128;
}
}
}



/*================================== YUV-RGB =================================*/
void yuv_to_rgb(float y[8][8],float u[8][8],float v[8][8],float r[8][8],float g[8][8],float b[8][8])
{
int i,j;

for ( i=0 ; i<8 ; i++ ){
for ( j=0 ; j<8 ; j++ ){
r[i][j]=y[i][j] +1.402 *(v[i][j]-128);
g[i][j]=y[i][j]-0.34414*(u[i][j]-128)-0.71414*(v[i][j]-128);
b[i][j]=y[i][j]+1.772 *(u[i][j]-128) ;
}
}
}

Asking other people to do your homework is frowned upon. You won't become a competent developer unless you learn to do things yourself.
