An object detection system for detecting instances of an object in a digital image includes an image integrator and an object detector, which includes a classifier (classification function) and image scanner. The image integrator receives an input image and calculates an integral image representation of the input image. The image scanner scans the image in same sized subwindows. The object detector uses a cascade of homogenous classification functions or classifiers to classify the subwindows as to whether each subwindow is likely to contain an instance of the object. Each classifier evaluates one or more features of the object to determine the presence of such features in a subwindow that would indicate the likelihood of an instance of the object in the subwindow.

Presented are systems and methods that provide a unified end-to-end detection pipeline for object detection that achieves impressive performance in detecting very small and highly overlapped objects in face and car images. Various embodiments of the present disclosure provide for an accurate and efficient one-stage FCN-based object detector that may be optimized end-to-end during training. Certain embodiments train the object detector on a single scale using jitter-augmentation integrated landmark localization information through joint multi-task learning to improve the performance and accuracy of end-to-end object detection. Various embodiments apply hard negative mining techniques during training to bootstrap detection performance. The presented are systems and methods are highly suitable for situations where region proposal generation methods may fail, and they outperform many existing sliding window fashion FCN detection frameworks when detecting objects at small scales and under heavy occlusion conditions.

An image cropping system utilizes memory, an object detector, and an image cropper. A set of digital data that defines a graphical image is stored in the memory. The object detector analyzes the set of digital data and automatically identifies a portion of the digital data that defines an image of a particular object. The image cropper then uses the identified portion to determine a position of the object image within the graphical image. Based on the position of the object image within the graphical image, the image cropper automatically crops the digital data. In this regard, the position of the object image within the graphical image serves as a reference for determining which portions of the set of digital data should be cropped.

Registration correction for optical tomographic imaging in three dimensions. An object of interest is illuminated to produce an image. A lateral offset correction value is determined for the image. An axial offset correction value is determined for the image. The lateral offset correction value and the axial offset correction value are applied to the image to produce a corrected file image.

An object detector, an object detecting method and a robot can reduce diction errors of detecting wrong objects without increasing the volume of the computational operation to be performed to detect the right object. A face detector 101 comprises a face detecting section 110 that operates like a conventional face detecting section and is adapted to roughly select face candidates from an input image by template matching and detect face candidates by means of a support vector machine for face recognition, a non-face judging section 120 that detects non-face candidates that are judged to be non-faces and removes them from the face candidates selected by the face detecting section 110 and a skin tracker section 114 for tracking a face region after the non-face judgment. When the assumed distance between the face detector and the face as computed from the input image and the measured distance as measured by a distance sensor show a large difference, when the color variance of the face candidate is small, when the occupancy ratio of the skin color region is large and when the change in the size of the face region is large after the elapse of a predetermined time, the non-face judging section 120 judges such face candidates as non-faces and removes them from the face candidates.

A stereoscopic camera includes first and second image pickup units, having respectively first and second optical axes, for photographing an object to form two image frames. Two angle adjusters make angle adjustment of the optical axes. An object detector detects a human face as a principal object in the two image frames. An arithmetic processor obtains a shift amount of the face between two image frames, and determines an axial correction angle according to the shift amount for the angle adjustment in consideration of the face. A checker checks whether the angle adjustment should be made for both optical axes or for one thereof. A controller operates at least one of the two angle adjusters according to the axial correction angle and in response to information from the checker, for positioning the face equally between the two image frames optically by adjusting the first and/or second optical axis.

An object position area (82a) is calculated according to a position in the space of a detected truck (70). A template (80a) corresponding to the object position area (82a) recorded at the previous time is then called. The template (80a) is moved to a position on a reference image I_b where the similarity is highest. Overlap rate (R_(t-1)⊥R_t) of the object position area (82a) and the template (80a) is calculated. A decision is made whether the object is identical to that detected in the past by using the overlap rate.

Techniques and systems are provided for tracking objects in a sequence of video frames. For example, an object tracker maintained for the sequence of video frames is identified. An object tracked by the object tracker is detected based on an application of an object detector to at least one key frame in the sequence of video frames. The object detector can include a complex object detector. A status of the object tracker can be updated to a still status in a current video frame of the sequence of video frames. A tracker having the still status is associated with an object that is static in one or more video frames of the sequence of video frames. The object can be tracked in the current video frame using the object tracker based on the status of the object tracker being updated to the still status in the current video frame. For example, a bounding region of the object tracker in the current frame can be replaced with a previous bounding region of the object tracker in a previous frame based on the status of the object tracker being updated to the still status in the current video frame.

A system and method for assisting the driver of a vehicle in identifying obstacles for the vehicle as is described. Objects located outside the vehicle are detected with the aid of object detector. If objects are detected, information is given to the driver and/or to defined components of the vehicle. An evaluation unit ascertains whether a detected object is a road bump, and information is given to the driver and/or to components of the vehicle only if a detected object is a road bump.

An object detector detects an object with a camera and calculates position data showing its direction and distance. A laser radar obtains an front image and recognizes an identified image in the front image. Coordinates of this identified image are calculated and converted to data indicating direction to the object. The identified image is correlated with the object detected by the laser radar and the correlated object is identified as an identified object. Position data of this correlated object are outputted as data on the identified object.

A method and system for training a special object detector to distinguish a foreground object appearing in a sequence of frames for a target domain. The sequence of frames depicts motion of the foreground object in a non-uniform background. The foreground object is detected in a high-confidence subwindow of an initial frame of the sequence, which includes computing a measure of confidence that the high-confidence subwindow includes the foreground object and determining that the measure of confidence exceeds a specified confidence threshold. The foreground object is tracked in respective positive subwindows of subsequent frames appearing after the initial frame. The subsequent frames are within a specified short period of time. The positive subwindows are used to train the special object detector to detect the foreground object in the target domain. The positive subwindows include the subwindow of the initial frame and the respective subwindows of the subsequent frames.
