Abstract
Systems and methods are provided for processing images captured by a capsule camera system. According to one method, a frame sequence comprises panoramic picture representative of a GI scene covering substantially a lateral 360-degree Field-of-View is received. CADe (computer-assisted detection) is applied to detect one or more target abnormalities in the frame sequence, where said applying the computer-assisted detection (CADe) results in one or more CADe frames and each CADe frame contains at least one detection area containing a detected abnormality or a false positive. Circle shift is applied laterally to a target CADe frame to shift a detection area to a lateral center or close to the lateral center of the target CADe frame. The CADe frames comprising the target CADe frame are provided with the detection area shifted to the lateral center or close to the lateral center of the target CADe frame.
Core Innovation
The invention relates to processing a frame sequence corresponding to gastrointestinal (GI) images, where each frame comprises a panoramic picture representative of a GI scene covering substantially a lateral 360-degree field of view. A CADe is applied to detect one or more target abnormalities in the frame sequence, generating one or more CADe frames, and each CADe frame contains at least one detection area comprising a detected abnormality or a false positive.
The invention further processes the CADe output by determining the horizontal location of the detection area in a target CADe frame. In response to the horizontal location, the target CADe frame is shifted laterally using circle shift laterally so that the detection area is shifted to a lateral center or close to the lateral center.
In addition, frames in the frame sequence are skipped for at least one pair of consecutive CADe frames. The CADe frames comprising the target CADe frame with the detection area shifted to the lateral center or close to the lateral center are provided for further viewing, and the processing is performed using program codes executable on one or more electronic devices or processors.
Claims Coverage
Two independent claims are provided. The claims include CADe-based generation of CADe frames with detection areas, skipping of frames between consecutive CADe frames, determination of horizontal location, and lateral circle shifting to move detection areas toward a lateral center or close to it.
CADe processing of lateral 360-degree panoramic GI frame sequence with skipped frames
Receiving the GI frame sequence with each frame comprising a panoramic picture covering substantially a lateral 360-degree field of view, applying CADe to detect one or more target abnormalities to generate CADe frames where each CADe frame contains detection areas comprising a detected abnormality or a false positive, and skipping one or more frames in the frame sequence for at least one pair of consecutive CADe frames.
Horizontal location determination and lateral circle shift to lateral center in CADe frames
Determining horizontal location of the at least one detection area in a target CADe frame, in response applying circle shift laterally to shift the detection area to a lateral center or close to the lateral center of the target CADe frame, and providing the CADe frames comprising the target CADe frame with the detection area shifted to the lateral center or close to the lateral center.
Program-code execution for CADe, horizontal location determination, and lateral circle shift
Performing the applying CADe to detect the one or more target abnormalities, the determining horizontal location of the detection area, and the applying circle shift laterally to the target CADe frame using program codes executable on one or more electronic devices or processors.
System modules for CADe, horizontal location determination, and lateral circle shift
An interface module receiving the GI panoramic frame sequence and processing modules configured to apply CADe to detect one or more target abnormalities generating CADe frames with detection areas comprising a detected abnormality or a false positive, skip one or more frames in the frame sequence for at least one pair of consecutive CADe frames, determine horizontal location of the detection area in a target CADe frame, apply circle shift laterally to shift the detection area to a lateral center or close to the lateral center, and provide the CADe frames comprising the target CADe frame with the detection area shifted to the lateral center or close to the lateral center, with the CADe, determining, and circle shift performed by program codes executable on one or more electronic devices or processors.
The core claim coverage centers on CADe generating CADe frames with detection areas, skipping between consecutive CADe frames, determining the detection area’s horizontal location, and applying lateral circle shift so the detection area is moved toward the lateral center, executed by program codes on electronic devices or processors.
