2-D DCT Value Generator

2-D DCT Value Generator

Generate a random 8 × 8 matrix and calculate only its DCT values step by step

📐 DCT Formula

D(u,v) = 1/4 × C(u) × C(v) × Σ Σ f(x,y) cos[(2x+1)uπ/16] cos[(2y+1)vπ/16]

C(0) = 1/√2     C(k) = 1 for k > 0

Step 1 — Random 8 × 8 Matrix

Step 2 — DCT Calculation

Click ▶ NEXT DCT VALUE to calculate the DCT coefficients one by one.

DCT Values Calculated: 0 / 64

Step 3 — DCT Values
