This correspondence presents a new pixel-recursive algorithm for estimating the nonuniform image motion from noisy measurements. The proposed method is performed in two steps. First, the pixels are examined to identify the (detectable) moving pixels, using a binary hypothesis testing. Then, characterizing the motion of the identified moving pixels in terms(More)
In this paper, we present an algorithm to simultaneously estimate multiple-frame motions and filter image sequences. The relative motion dk(x) between the reference frame s(x) and the kth frame s(x-dk(x)) in the presence of additive white Gaussian noise (AWGN) is estimated using the maximum-likelihood (ML) principle. The reference frame is also filtered in(More)
The purpose of these guidelines is to recommend appropriate imaging for patients with blunt chest trauma. These patients are most often imaged in the emergency room, and thus emergency radiologists play a substantial role in prompt, accurate diagnoses that, in turn, can lead to life-saving interventions. The ACR Appropriateness Criteria® are evidence-based(More)
