  • Patent number: 10657629
    Abstract: A memory stores image data generated by sensors included in an imager and containing a component data piece for each of color components that has undergone A/D conversion by an A/D converter. A width detector detects, based on the image data having undergone image processing by an image processor, the width along the main scanning direction of a duplicate area in which pieces of image data generated by adjoining sensors overlap each other. A displacement detector detects, based on the width of the duplicate area along the main scanning direction, a displacement of a scan target object for each of optical systems included in the imager. A first blur corrector performs blur correction on the component data piece using a point spread function for each of the color components that is dependent on a displacement of the scan target object.

  • Patent number: 10643313
    Abstract: Systems and methods related to pre-processing images and estimating PSFs for image deblurring in a noise-robust manner. The pre-processing may include iteratively denoising a reference image, iteratively denoising a scene image containing at least one straight edge within the scene image while preserving the at least one straight edge. The pre-processing may include smoothing, subtracting and dividing to provide a pre-processed image. The PSF-estimation process may include generating, with the at least one processor, a first noise value from portions of an edge intensity profile, generating a second noise value from a difference between the edge intensity profile and an integral of the noise-regularized inversion of the integration operator operating on the edge intensity profile and determining a value of a local curvature regularization parameter resulting in the first noise value and the second noise value being within a tolerance range.

  • Patent number: 10635929
    Abstract: The present invention belongs to the field of machine vision. A saliency-based method for extracting a road target from a night vision infrared image is disclosed. The method combines saliencies of the time domain and the frequency domain, global contrast and local contrast, and low level features and high level features, and energy radiation is also considered to be a saliency factor; thus, the object of processing is an infrared image and not the usual natural image. The extraction of a salient region is performed on the raw natural image on the basis of energy radiation, and the obtained extraction result if the salient region is more accurate and thorough, and the contour of a target in the salient region is clearer.

  • Patent number: 10591731
    Abstract: A system and method for ocular stabilization of video images is disclosed. While capturing video images in a forward field of view with a forward-facing video camera of a wearable head-mountable device (HMD), binocular eye-gaze directions of left and right eyes of a user of the HMD may be obtained with an eye-tracking device of the HMD. Based on the obtained binocular eye-gaze directions of left and right eyes of the user of the HMD, convergent gaze directions of the user may be determined as a function of time during an interval concurrent with the capturing of the video images. The captured video images may then be stabilized by compensating for motion of the forward-facing video camera with an intersection of the convergent gaze directions of the user with an image plane of the forward-facing video camera.

  • Patent number: 10547784
    Abstract: A camera having a gyro and accelerometer stabilizes a video recording by the following steps. First, gyro data and acceleration data are synchronized with a frame of video data. The gyro data and the acceleration data are fused together to get a space domain rotation matrix that corresponds to the frame. The frame is adjusted based on the space domain rotation matrix. Next, at least one feature of the adjusted frame is detected. A modified rotation matrix is determined by comparing the at least one detected feature of the adjusted frame with a corresponding feature in a neighboring frame of the video data. Finally, the adjusted frame is further adjusted based on the modified rotation matrix.
