The work presents a robust rate control algorithm for JPEG compression, mainly used in digital cameras. The overall control is based on the statistical properties of JPEG compressed images, the relationship between the coding bit rate and the percentage of zeros among the quantized transform coefficients. It allows a good trade off between resources and precision to be obtained.
