I'm really sorry, I just notice that it's a stupid mistake from me... I forgot to change the template parameter of the concolve_rows function !
If I use k_channel_view I manipulate a grayscale image...

kernel_1d<float> kernel2(gaussian_1,9,4);
convolve_rows<gray32f_pixel_t>(kth_channel_view<0>(const_view(img)),kernel2,kth_channel_view<0>(view(img)));
jpeg_write_view("out-convolution2.jpg", view(img));
