CORRECTING SPACECRAFT JITTER IN HIRISE IMAGES

Efficient Jitter Analysis for Spacecraft

TRANSIENT AEOLIAN FEATURES DETECTED AUTONOMOUSLY IN HiRISE IMAGES OF EL

Introduction: Since the 1970s, images taken of Mars have shown the presence of transient aeolian features such as dust devil tracks, bedforms and windstreaks. High-resolution images of a small portion of Gusev crater were chosen to test the development of autonomous recognition algorithms for these transient features. A pair of images representing a difference of three years in time was analyze...

Continuing Analysis of Spacecraft Jitter in Lroc-nac

Introduction: The Lunar Reconnaissance Orbiter (LRO) has been flying in its nominal, or mapping, orbit of ~50 km above the surface of the Moon since September 15, 2009 [1]. The Lunar Reconnaissance Orbiter Camera Narrow Angle Camera (LROC-NAC) takes high resolution images using two identical line scan cameras (NACL and NACR) with pointing offset from each other by ~2.79o cross-track and ~0.082o...

Small Impact Crater Clusters in High Resolution Hirise Images

Introduction: Impact crater clusters or crater strewn fields from primary impacts are found in MOC [1, 2], CTX, and HiRISE images [3, 4]. We present the analysis of new data on small craters and crater clusters accumulated by the HiRISE team for the first 10,000 orbits of MRO. New Craters on Mars: Repetitive imaging of Mars by various spacecraft revealed 20 potential " new " impact sites [2]: i...

Color Correcting JPEG Compressed Images

Many high end printing systems store and/or transmit compressed images to save bandwidth, memory, and disk space. Prior to printing, the system will decompress and then color correct the image to compensate for the characteristics of a particular printer. In the conventional architecture, the decompression step converts the image from some encoded format (e.g. JPEG with Huffman encoding) into t...
