Abstract: An image coding system includes an image encoder and a predictive image decoder. The image encoder encodes an input image to obtain encoded data, compares the input image with a reference image, generates error information identifying parts of the input image that are changed with respect to the reference image, and outputs the encoded data and the error information. The predictive image decoder predicts the image, using a simplified prediction method for parts of the image identified by the error information as not being changed, and decodes the encoded data and the predicted data to obtain decoded image data. Use of the simplified prediction method in unchanged parts of the image reduces the prediction processing load without significant loss of prediction accuracy.

Abstract: A method maintaining an image background by multiple Gaussian models utilized to a device includes the following steps. First, the device captures an image frame having pixels to obtain background information, and then calculates the background information to establish a primary Gaussian model. Next, the device captures continuous image frames in a time period to obtain and calculate graphic information for establishing a secondary Gaussian model, and then repeates the steps to establish multiple secondary Gaussian models. Finally, the device compares two secondary Gaussian models, and then updates learning for the primary Gaussian model by the secondary Gaussian model if the graphic information of the secondary Gaussian models are attributable to the background information, or maintains the background information of the primary Gaussian model without updating the learning if anyone of the graphic information of the two secondary Gaussian models is unattributable to the background information.
