Description

The Joint Photographic Experts Group (JPEG) format was born on 18 September 1992 under the name Project Nayuki. Although other compression formats were already available at the time, JPEG became the global standard, partly because it was royalty-free. So this year we celebrate its 30th anniversary! The discrete cosine transform, the underlying idea behind JPEG. | Project Nayuki : double *NaiveDct_transform(double vector[], size_t len) { if (SIZE_MAX / sizeof(double) < len) return NULL; double *result = malloc(len * sizeof(double)); if (result == NULL) return NULL; double factor = M_PI / len; for (size_t i = 0; i < len; i++) { double sum = 0; for (size_t j = 0; j < len; j++) sum += vector[j] * cos((j + 0.5) * i * factor); result[i] = sum; } return result; } EZ3 2022 - HAM THE ASTRO CHIMP RIP Alotta Money
