Patent Images
1. A system, comprising:
- a detection circuit configured to acquire one or more micrographs of a biological sample at one or more fields of view;
a resolution modification circuit configured to modify a pixel count of at least one micrograph and to generate at least a first modified micrograph;
a filter-kernel generation circuit configured to generate a kernel for filtering a plurality of pixels forming the first modified micrograph based on a filtering characteristic, and to generate at least a first significance image representative of the at least one modified micrograph; and
an object identification circuit configured to identify groups of pixels in the first significance image indicative of one or more objects imaged in the at least one micrograph, and to generate one or more connected components of a graph representative of groups of pixels indicative of the one or more objects imaged in the at least one micrograph,wherein the object identification circuit is configured to determine a probability that the biological sample is infected with malaria, and to determine a confidence level associated with the determined probability that the biological sample is infected with malaria.

13. A method, comprising:
-
acquiring, using a detection circuit, one or more micrographs of a biological sample at one or more fields of view; modifying a resolution of at least one of the one or more micrographs and generating at least a first modified micrograph; generating a first filtered micrograph by filtering the at least first modified micrograph based on a filtering protocol; and determining a disease state by identifying objects of the biological sample in the filtered micrograph. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
