High-accuracy differential image motion monitor measurements for the Thirty Meter Telescope site testing program.
Differential image motion monitors (DIMMs) have become the industry standard for astronomical site characterization. The calibration of DIMMs is generally considered to be routine, but we show that particular care must be paid to this issue if high-accuracy measurements are to be achieved. In a side by side comparison of several DIMMs, we demonstrate that with proper care we can achieve an agre...
متن کاملFrom Differential Image Motion to Seeing
The theory of the differential image motion monitor (DIMM), a standard and widely spread method of measuring astronomical seeing, is reviewed and extended. More accurate coefficients for computing the Fried parameter from the measured variance of image motion are given. They are tested by numerical simulations that show that any DIMM measures Zernike tilts, not image centroids as generally assu...
متن کاملMotion Differential SPIHT for Image Sequence Coding
Ef cient image sequence coding exploits both intraand interframe correlations. SPIHT is ef cient in intra-frame decorrelation for still images. Based on SPIHT, differential-SPIHT removes inter-frame redundancy by reusing the signi cance map of a SPIHT coded frame. The motion differential SPIHT (MD-SPIHT) automatically decides the coding methods for each frame, according to the inter-frame corre...
متن کاملMotion Recovery from Image Sequences: Discrete Viewpoint vs. Differential Viewpoint
The aim of this paper is to explore intrinsic geometric methods of recovering the three dimensional motion of a moving camera from a sequence of images. Generic similarities between the discrete approach and the differential approach are revealed through a parallel development of their analogous motion estimation theories. We begin with a brief review of the (discrete) essential matrix approach...
