This paper proposes a simple yet effective mechanism to select proper reference frames for H.264 motion estimation. Unlike traditional video codecs, H.264 permits more than one reference frame for increased precision in motion estimation. However, motion estimation is complicated by variable block-size motion estimation, which requires significant encoding(More)
This paper proposes an effective mechanism to select the dynamic search range for the H.264 multiple reference frames motion estimation with variable block sizes. Our dynamic search range control mechanism divides the search range into different zones determined by the block mode and reference frame of the target macroblock. In each zone, the search range(More)

The elderly population will approach 20% within the next 20 years. This enhances the need for skilled and experienced health care providers. There is a critical need to strengthen gerontology curricula to prepare health-related professionals for a graying population. The purpose of this article is to investigate student satisfaction with the first National(More)
OBJECTIVE Lymph node yield is recommended as a benchmark of quality care in colorectal cancer. The objective of this study was to evaluate the impact of various factors upon lymph node yield and to identify independent factors associated with lymph node harvest. MATERIALS AND METHODS The records of 162 patients with Stage I to Stage III colorectal cancers(More)
