A joint position estimation device including a memory, and a processor connected to the memory. The processor executes a process including estimating, by a first DNN for which a first parameter determined by learning of the first DNN has been set, a body part region of the animal with respect to input image to be processed; and estimating, by the second DNN for which a second parameter determined by learning of the second DNN has been set, a first joint position and a second joint position in each of the body part region estimated by the first DNN and a plural body parts region in which a plurality of the body part regions are connected.

Joint position estimation device, joint position estimation method, and joint position estimation program

A non-transitory computer-readable recording medium having stored therein an information processing program for causing a computer to execute a process includes: calculating, by using an image including an object having a plurality of joints and having a plurality of frames consecutive in time, a probability distribution of a joint position of the object in each frame; calculating a transition score by evaluating a consistency of a transition of a joint of the plurality of joints using transition information of the joint among different frames; and estimating a pose of the object from a score of the probability distribution and the transition score.

Information processing apparatus, information processing method, and information processing system

An information processing device includes: a memory; and a processor coupled to the memory and configured to: estimate a first position of a first joint in a two-dimensional plane based on a color image, and estimate a first positional relationship between the first joint and a second joint coupled to the first joint via a portion in the two-dimensional plane; estimate a second position of the first joint in the two-dimensional plane based on a depth image indicating respective depths of the first joint and the second joint, and estimate a second positional relationship between the first joint and the second joint in a three-dimensional space; and estimate a third position of the first joint in the two-dimensional plane and posture of the portion in the three-dimensional space based on the first position, the first positional relationship the second position, and the second positional relationship.

Information processing device, information processing method, and recording medium

An apparatus includes a first sensor device, a second sensor device and a first processor coupled to the first sensor device and the second sensor device and configured to calculate a probability that the apparatus is in a first state, based on a measurement of the first sensor device, initiate an operation of the second sensor device when the probability exceeds a first value, execute, based on a measurement of the second sensor device, a first detection that detects the apparatus is in a second state, execute, based on the measurement of the first sensor, a second detection that detects the probability exceeds a second value greater than the first value and that the apparatus is in the first state, and based on the first detection and the second detection, output a notification that indicates the apparatus is in both the first state and the second state.
