An Automated, Dynamic Threshold Cloud Detection Algorithm
نویسنده
چکیده
An operational scheme for cloud detection for FY-2C data is presented. The scheme consists of two major parts: total cloud detection and high cloud detection. Cloud detection separates cloud from underline surface, for every pixel, it is either clear pixel or is cloudy pixel. High cloud detection separates high cloud from other cloud types.

متن کاملA Threshold Accepting Algorithm for Partitioning Machines in a Tandem Automated Guided Vehicle
Abstract : A tandem automated guided vehicle (AGV) system deals with grouping workstations into some non-overlapping zones , and assigning exactly one AGV to each zone. This paper presents a new non-linear integer mathematical model to group n machines into N loops that minimizes both inter and intra-loop flows simultaneously. Due to computational difficulties of exact methods in solving our pr...
متن کاملCloud Clearing Techniques over Land for Land Surface Temperature Retrieval from the Advanced Along Track Scanning Radiometer
We present five new cloud detection algorithms over land based on dynamic threshold or Bayesian techniques, applicable to the Advanced Along Track Scanning Radiometer (AATSR) instrument and compare these with the standard threshold based SADIST cloud detection scheme. We use a manually classified dataset as a reference to assess algorithm performance and quantify the impact of each cloud detect...
