Abstract
An example method includes capturing a plurality of images of a rotating object using an imaging device optically coupled to a microscope. The method removing a first portion of a model of the rotating object based on a first contour of the rotating object in a first image of the plurality of images. The method includes orienting the model based on an amount of rotation of the rotating object between capture of the first image and capture of a second image of the plurality of images. The method also includes removing a second portion of the model of the rotating object based on a second contour of the rotating object in the second image.
Claims15
A system comprising:
- a substrate including a plurality of electrodes;
- a controller to apply a voltage to the plurality of electrodes to create an electric field to rotate an object suspended in a fluid;
- an imaging device to capture a plurality of images of the object;
- and
- a comparison engine to:
- determine a spatial relationship between the imaging device and the object for each image,
- compare a projection of a model of the object to a respective contour of the object in each image, an orientation of the projection corresponding to the spatial relationship between the imaging device and the object;
- and
- a modeling engine to modify the model of the object to more closely correspond to the respective contour of the object in each image.
A method, comprising:
- capturing a plurality of images of a rotating object using an imaging device optically coupled to a microscope;
- removing a first portion of a model of the rotating object based on a first contour of the rotating object in a first image of the plurality of images;
- orienting the model based on an amount of rotation of the rotating object between capture of the first image and capture of a second image of the plurality of images;
- and
- removing a second portion of the model of the rotating object based on a second contour of the rotating object in the second image.
A non-transitory computer-readable medium comprising instructions that, when executed by a processor, cause the processor to:
- determine a spatial relationship between an object in each of a plurality of images and an imaging device used to capture the plurality of images based on a rate of rotation of the object and a timing of image capture;
- generate a plurality of object contours based on the plurality of images, each contour generated from a corresponding one of the plurality of images;
- remove a plurality of volume elements (voxels) from a model of the object based on comparing the plurality of voxels to the plurality of object contours according to the spatial relationship for each image;
- and
- generate a representation of a surface of the object based on the model.
