Abstract: The disclosure proposes a method of fixed-rate line-based embedded video compression and an image processing apparatus using the same method. The method includes at least the following steps. A current encoding frame is received. Pixels in a current encoding frame are grouped on a line-by-line basis, and the grouped pixels are packed into pixel segments. Complexity information of a current pixel segment is calculated according to the pixels therein and neighboring pixels thereof. The current pixel segment is respectively encoded in a differential pulse-coding modulation (DPCM) mode and a truncation mode to generate a DPCM bitstream and a truncated bitstream according to a quantization parameter (QP). Either the DPCM bitstream or the truncated bitstream is selected and outputted according to the complexity information. An amount of bits used by the current pixel segment is feedback to calculate a new QP corresponding to a next pixel segment to be processed.

Abstract: A training method for video stabilization and an image processing device using the same are proposed. The method includes the following steps. An input video including low dynamic range (LDR) images is received. The LDR images are converted to high dynamic range (HDR) images by using a first neural network. A feature extraction process is performed to obtain features based on the LDR images and the HDR images. A second neural network for video stabilization is trained according to the LDR images and the HDR images based on a loss function by minimizing a loss value of the loss function to generate stabilized HDR images in a time-dependent manner, where the loss value of the loss function depends upon the features. An HDR classifier is constructed according to the LDR images and the HDR images. The stabilized HDR images are classified by using the HDR classifier to generate a reward value, where the loss value of the loss function further depends upon the reward value.
