Method for minimizing scintillation in dynamic images

A non-transitory computer-readable storage medium comprising a plurality of computer-readable instructions tangibly embodied on the computer-readable storage medium, which, when executed by a data processor, provide for minimizing scintillation while retaining moving objects in an image of a scene, the plurality of instructions comprising:

• instructions that cause the data processor to receive an input sequence of images of the scene;
• instructions that cause the data processor to group a first plurality of images of the sequence of images into a first subset of images comprising a first number of images that occur in sequence within the input sequence of images of the scene;
• instructions that cause the data processor to group a second plurality of images of the sequence of images into a second subset of images comprising a second number of images that occur in sequence within the input sequence of images of the scene, wherein a last image in the first subset of images occurs in time before a first image of the second subset of images;
• instructions that cause the data processor to generate a set of averaged images comprising an averaged image for the first subset of images and an averaged image for the second subset of images, wherein the step of generating the combined images comprising:
• selecting the first subset of images as a reference subset images;
• selecting averaged image of the first subset of images as a reference average image;
• creating a set of different images, wherein each different image of the set of difference images corresponds to an averaged image that is not the reference averaged image, wherein each difference image is created by subtracting the averaged image by subtracting the average image that corresponding to each difference image;
• creating a composite mask that determines at least one region of the averaged reference subset of images to be replaced using at least the set of masked images and the particular masked image;
• and creating a composite image using at least the composite mask and the averaged reference subset of images;
• and
• instructions that cause the data processor to output a composite image based at least on the set of averaged images.

• an image detection unit;
• and
• an image acquisition unit in communication with the image detection unit, and having a memory and a processing unit coupled to the memory;
• wherein the processing unit is configured to execute a method for minimizing scintillation while retaining moving objects in an image of a scene, the method comprising:

• grouping a first set of images of the sequence of images into a first subset of images comprising a first number of images that occur in sequence within the input sequence of images of the scene;
• grouping a second set of images of the sequence of images into a second subset of images comprising a second number of images that occur in sequence within the input sequence of images of the scene, wherein a last image in the first subset of images occurs in time before a first image of the second subset of images,
• generating a set of statistically combined images comprising an statistically combined image for the first subset of images and an statistically combined image for the second subset of images, wherein the step of generating the combined images comprising:
• selecting the first subset of images as a reference subset images;
• selecting averaged image of the first subset of images as a reference average image;
• creating a set of different images, wherein each different image of the set of difference images corresponds to an averaged image that is not the reference averaged image, wherein each difference image is created by subtracting the averaged image by subtracting the average image that corresponding to each difference image;
• creating a composite mask that determines at least one region of the averaged reference subset of images to be replaced using at least the set of masked images and the particular masked image;
• and creating a composite image using at least the composite mask and the averaged reference subset of images;
• and
• outputting a composite image based at least on the set of statistically combined images.
