An energy management system for use with off-highway vehicles, including locomotives, that traverse a known course. A processor determines power storage and transfer parameters, including data indicative of present and future track profile information. The energy management system controls the storage and regeneration of electrical energy. A hybrid energy locomotive system has an energy storage and regeneration system. In one form, the system can be retrofitted into existing locomotives or installed as original equipment. The energy storage and regeneration system captures dynamic braking energy, excess motor energy, and or externally supplied energy. The captured energy is stored in an energy storage system such as a battery, a flywheel system, or a capacitor system. The energy storage and regeneration system can be located in a separate energy tender vehicle. The separate energy tender vehicle is optionally equipped with traction motors.

The respective corresponding weighting coefficient Wjfor each errors Ejare determined. Then, a resultant gray value Riof the focus pixel is calculated by Ri=Gi+ΣWj(Ej-C), wherein C is a programmable integer. Thereafter, the gray value Riis dividing into most significant part Miand least significant part Li,wherein Miis a K-bit integer, Liis an (N-K)-bit integer, Mi×2N-K+Li=Ri,and -2N-K/2≤LiN-K/2. The error Eiof the focus pixel is stored as Liplus an error bias D of 2N-K/2. Finally, the focus pixel is displayed using Mias the degraded target gray value. igital image; b) determining whether an output image value is a predetermined high level or low level based on the threshold; c) if the input pixel value is greater than the threshold and the output image value is the predetermined high level, modulating the threshold of the adjacent pixel as: t(m+p, n+q)+=Tf1(p,q)×t(m,n), wherein t(m,n) is the threshold of the (m,n)-th pixel being the current input pixel, t(m+p, n+q) is the threshold of the pixel separated from the (m,n)-th pixel by (p,q), and Tf1(p,q) is a first threshold modulation coefficient; d) if the input pixel value is greater than the threshold and the output image value is the predetermined low level, modulating the threshold of the adjacent pixel as: t(m+p, n+q)+=Tf2, wherein t(m,n) is the threshold of the (m,n)-th pixel being current input pixel, t(m+p, n+q) is the threshold of the pixel separated from the (m,n)-th pixel by (p,q), and Tf2is a second threshold modulation coefficient; e) if the input pixel value is not greater than the threshold and the output image value is the predetermined low level, modulating the threshold of the adjacent pixel as: t(m+p, n+q)-=Tf1(p,q)×t(m,n), wherein t(m,n) is the threshold of the (m,n)-th pixel being the current input pixel, t(m+p, n+q) is the threshold of the pixel separated from the (m,n)th pixel by (p,q), and Tf1(p,q) is a first threshold modulation coefficient; and f) if the input pixel value is not greater than the threshold and the output image value is the predetermined high level, modulating the threshold of the adjacent pixel as: t(m+p, n+q)-=Tf2, wherein t(m,n) is the threshold of the (m,n)th pixel being the currently input pixel, t(m+p, n+q) is the threshold of the pixel separated from the (m,n)th pixel by (p,q), and Tf2is a second threshold modulation coefficient. 5.
