fixed a bug in d_smooth_r/g/b and t_smooth_r/g/b declaration in gbh.cu, // smooth_r, smooth_g, smooth_b size, 207         int num_smooth = num_cores * num_vertices; // allocate space for t_smooth_r/g/b in CPU, 208         int num_smooth_s = num_cores * num_vertices * sizeof(float); // allocate space for d_smooth_r/g/b in GPU, // allocate gpu space for smooth_r, smooth_g, smooth_b , 249         float* d_smooth_r; cudaMalloc((void**)&d_smooth_r, num_smooth_s);, 252         float* t_smooth_r = new float[num_smooth];, // copy image data from cpu to gpu, 269         cudaMemcpy(d_smooth_r, t_smooth_r, num_smooth_s, cudaMemcpyHostToDevice);
