Abstract
Methods and systems for non-stationary image sensor frame registration include receiving a data capture from an image sensor in motion, spatially filtering at least one pixel intensity value within the data capture to create a spatially filtered image, predictively differencing a filtered pixel intensity value of the spatially filtered image from a predicted intensity value, and generating a predictively differenced image based on the predictive differencing.
Claims20
A method for frame registration for an image sensor in motion comprising the steps of:
- receiving, at a computing device, a data capture from an image sensor in motion;
- spatially filtering, by a processing component of the computing device, at least one pixel intensity value within the data capture to create a spatially filtered image;
- predictively differencing, by the processing component of the computing device, a filtered pixel intensity value of the spatially filtered image from a predicted intensity value, the predicted intensity value being a linear projection based on previous filtered pixel intensity values of a corresponding pixel in at least two previously filtered images stored in a memory component of the computing device;
- and
- generating a predictively differenced image based on the predictive differencing.
A mobile imaging system comprising:
- an image sensor secured to a mobile host platform and configured to capture image data;
- and
- a computing device in electronic communication with the image sensor and having a memory component and a processing component, the memory component including instructions that, when executed by the processing component, cause the computing device to:
- receive a data capture from the image sensor,
- spatially filter at least one pixel intensity value within the data capture to create a spatially filtered image,
- predictively difference a filtered pixel intensity value of the spatially filtered image from a predicted intensity value, the predicted intensity value being a linear projection based on previous filtered pixel intensity values of a corresponding pixel in at least two previously filtered images stored in a memory component of the computing device, and
- generate a predictively differenced image based on the predictive differencing.
A mobile imaging system comprising:
- a plurality of image sensors installed on a common mobile host platform, each of the image sensors configured to capture image data;
- a plurality of dedicated computing devices installed on the common mobile host platform, each of the dedicated computing devices in electronic communication with a corresponding one of the plurality of image sensors and having a memory component and a processing component, the memory component including instructions that, when executed by the processing component, cause the dedicated computing device to:
- receive a data capture from the corresponding one of the plurality of image sensors,
- spatially filter at least one pixel intensity value within the data capture to create a spatially filtered image, and
- predictively difference a filtered pixel intensity value of the spatially filtered image from a predicted intensity value, the predicted intensity value being a linear projection based on previous filtered pixel intensity values of a corresponding pixel in at least two previously filtered images stored in a memory component of the dedicated computing device, and
- generate a predictively differenced image based on the predictive differencing.
