Abstract: To improve accuracy of estimating a pose of a photographed object, provided is target region acquisition means (21) determines whether or not the input image includes an image of a target object by inputting at least a part of an input image to a classification model trained based on a plurality of learning images including an image in which a target object has been photographed and label data indicating whether or not each of the learning images includes the target object, and acquires a target region including the image of the target object, which is extracted from the input image. Pose estimation means (25) estimates a pose of the target object based on information output by a machine learning model, when the acquired target region is input thereto, which is trained by: a plurality of training images rendered by a three-dimensional shape model of the target object; and ground truth data being information relating to the pose of the target object in the training images.

Abstract: An image generation apparatus 200 includes a distortion information storage section 234 that stores, as distortion information, information for deforming and distorting an image, and a distortion rendering section 232 that renders a distorted image by rasterization processing using the distortion information without generating a non-distorted image in a memory. The distortion rendering section 232 renders the distorted image by executing the rasterization processing on a distorted triangle obtained by transforming a triangle to be rasterized on the basis of the distortion information such that the processing is executed upward and downward from positions of vertices of the distorted triangle.

Abstract: This information processing apparatus allows a video display apparatus (40) worn on a head and used by a user to display a stereoscopic video including an object to be operated, and receives a gesture operation to the object by moving a hand by the user, when there is a match between a recognition position in which the user recognizes that the object is present in a real space and a shifted position deviated from a position of the hand of the user by a predetermined amount in the real space.

Abstract: Provided is a system including an event-driven vision sensor including a sensor array in which a first sensor and a second sensor are arrayed in a predetermined pattern, the first sensor being configured to generate a first event signal when detecting a change in intensity of light larger than a first threshold, the second sensor being configured to generate a second event signal when detecting a change in intensity of light larger than a second threshold larger than the first threshold, and an information processing device including a first processing unit configured to execute first processing when the first event signal is received and the second event signal is not received, and a second processing unit configured to execute second processing different from the first processing when the second event signal is received.

Abstract: An imaging apparatus 12 acquires RAW images 202a and 202b by left and right cameras and performs a demosaicing process for and stepwise reduction of the RAW images 202a and 202b to generate and correct colored image groups 204a and 204b which represent picked up images with a plurality of resolutions (S10 and S12). Image process parameters 206 acquired in the course of the demosaicing process and the correction process are transmitted to a host terminal 20 together with part of colored images and data of a partial image 208 of the RAW image 202a. The host terminal 20 utilizes the image process parameters 206 transmitted from the imaging apparatus 12 to perform a demosaicing process for the partial image 208 to generate and correct a colored image 212 (S16). The host terminal 20 utilizes the colored image transmitted from the imaging apparatus 12 and the colored image 212 generated therein to generate an image 214 to be displayed (S18 and S20).

Abstract: Irradiation light from a sensor is separated into transmission light and reflected light through a one-way mirror to reach objects that are present in a plurality of directions. The one-way mirror concentrates the reflected light on the sensor. A position information acquisition device detects a local maximum point in a change in a degree of photons observed by the sensor, thereby acquiring path lengths of light to objects to generate position information on the basis of the position and the posture of the one-way mirror from the sensor.

Abstract: Pulsed light emitted from a light emitter of a TOF sensor at an intensity is divided into light that is reflected by an object having transmissivity and reaches a light receiver at an intensity and light that passes through the object and reaches an object at an intensity. The latter is reflected by the object at an intensity, partly passing through the object to reach the light receiver at an intensity. A local maximum point is detected in a change in a degree of photons observed by the light receiver, to acquire both distances to the object and the object.

Abstract: As a user guide, the state of overlooking a real space including an imaging device and a user is presented by one of two images: an image in reference to the position of the imaging device, or an image in reference to the user's direction. In both images, a rectangle indicative of the imaging device and a circle representative of the user are presented in a manner reflecting the actual positional relations and directions involved. Also presented are an area denoting a play area in the horizontal direction determined by a camera angle of view for example, and an arrow pointing to the direction in which the user is to move.
