This paper is a study of Gustav Deutsch's film (2013). The film transformed the painting of Edward Hopper into an homage film. So it gives the impression that the picture is moving. In this regard, it raises the issue of 'remediation' between film and pictures. In this study, We ask how (2013) dealt with the movement in turning Hopper's paintings into movies. To that end, To this end, we look at two aspects of movement: the actor's movement and the screen's movement. The concepts of "tableau vivant," Agamben's gesture and mediation were used in the process. The actor's movement in the film is not an act of making and developing events. It is a gesture that moves a person's body and expression itself. It is not a story-oriented acting, but a gesture that Giorgio Agamben said. Editing and camera movements are used while maintaining frontality. This suggests that the movement of the screen is the eye of the audience. At first glance, it embodies the voyeuristic gaze of the original work. However, But the audience isn't looking at the image unilaterally, as in mainstream fiction films, but they are also being seen by that image. Also, the camera's movement to take a closer look at the details of the screen shows the movement itself rather than the means to reveal the details. The 'vision of reality' in a film is made through movement. The film questions the vision of reality between painting and film, between words and images. The move is a means of mediating reality, but the film is regaining the "lost gesture" that Giorgio Agamben once said by revealing its mediated nature. This tells us that the vision of reality appears when it obscures its mediated nature.

The position detection of overlapping area in the interframe for image stitching using auto and cross correlation function (ACCF) and compounding one image with the stitching algorithm is presented in this paper. ACCF is used by autocorrelation to the featured area to extract the filter mask in the reference (previous) image and the comparing (current) image is used by crosscorrelation. The stitching is detected by the position of high correlation, and aligns and stitches the image in shifting the current image based on the moving vector. The ACCF technique results in a few computations and simplicity because the filter mask is given by the featuring block, and the position is enabled to detect a bit movement. Input image captured from CMOS is used to be compared with the performance between the ACCF and the window correlation. The results of ACCF show that there is no seam and distortion at the joint parts in the stitched image, and the detection performance of the moving vector is improved to 12% in comparison with the window correlation method.

In this paper, we describe image matching techniques which is automatically retrieving the exact matching area using geometry-phase information. We proposed a Matching Method which is rapidly estimating the correspondent points between adjacent images that included big-rotation and top-bottom movement element. It is a method that reduce computation quantity to be required to find an exact correspondent position using geometry-phase information of extracted points in images and DT map which set the distance value among feature points and other points on the basis of each feature point of a image. The proposed method shows good performance especially in the part to search a exact correspondent position between adjacent images that included big-rotation and top-bottom movement element.

If vibration occurs due to fast movement of the robot, the camera image is unstable. No longer the eyes of a robot can not perform the role. Research methods for the stabilization of shaky video is required. The most popular method is to use the motion vector. But, the drawback to this method will require a large amount of operation. And the limits of the embedded robot. Therefore, in real-time transmission of images to be difficult. This paper proposes a motion sensor using the image stabilization. Uses data that is output from the motion sensor. So, not related to the progress of the robot movement is a way to remove it from the video.

Eye movements serve vision by placing the image of an object on the fovea of each retina, and by preventing slippage of images on the retina. The brain employs two modes of ocular motor control, fast eye movements (saccades) and smooth eye movements. Saccades bring the fovea to a target, and smooth eye movements prevent retinal image slip. Smooth eye movements comprise smooth pursuit, the optokinetic reflex, the vestibulo-ocular reflex (VOR), vergence, and fixation. Saccades achieve rapid refixation of targets that fall on the extrafoveal retina by moving the eyes at peak velocities that can exceed $700^{\circ}/s$. Various brain lesions can affect saccadic latency, velocity, or accuracy. Smooth pursuit maintains fixation of a slowly moving target. The pursuit system responds to slippage of an image near the fovea in order to accelerate the eyes to a velocity that matches that of the target. When smooth eye movements velocity fails to match target velocity, catch-up saccades are used to compensate for limited smooth pursuit velocities. The VOR subserves vision by generating conjugate eye movements that are equal and opposite to head movements. If the VOR gain (the ratio of eye velocity to head velocity) is too high or too low, the target image is off the fovea, and head motion causes oscillopsia, an illusory to-and-fro movement of the environment.

Theoretical analysis of the depth measurement system with the use of a single camera and a rotating mirror has been done. A camera in front of a rotating mirror acquires a sequence of reflected images, from which depth information is extracted. For an object point at a longer distance, the corresponding pixel in the sequence of images moves at a higher speed. Depth measurement based on such pixel movement is investigated. Since the mirror rotates along an axis that is in parallel with the vertical axis of the image plane, the image of an object will only move horizontally. This eases the task of finding corresponding image points. In this paper, the principle of the depth measurement-based on the relation of the pixel movement speed and the depth of objects have been investigated. Also, necessary mathematics to implement the technique is derived and presented. The factors affecting the measurement precision have been studied. Analysis shows that the measurement error increases with the increase of depth. The rotational angle of the mirror between two image-takings also affects the measurement precision. Experimental results using the real camera-mirror setup are reported.

This paper presents an efficient object selection algorithm by analyzing and detecting of human activity. Generally, when people point any something, they will put a face on the target direction. Therefore, the direction of the face and fingers and was ordered to be connected to a straight line. At first, in order to detect the moving objects from the input frames, we extract the interesting objects in real time using background subtraction. And the judgment of movement is determined by Principal Component Analysis and a designated time period. When user is motionless, we estimate the user's indication by estimation in relation to vector from the head to the hand. Through experiments using the multiple views, we confirm that the proposed algorithm can estimate the movement and indication of user more efficiently.

To understand the biomechanics of the mandibular movement of the patients with T.M.J. disorder, it is necessary to analyze the mandibular movement by the least moving points of instantaneous center of rotation on computer screen. In this study, two subjects without T.M.J. disorder and with normal occlusion and few patients with T.M.J. disorder were selected for obtaining the processing data. The habitual opening and dosing movements were recorded by image recognition system of video and computer and then the mandibular movement and the least moving point were analyzed using computer program for image anaysis of specialized points. The results obtained were as follows: 1. The least moving points of control group during opening and dosing were dose to the mandibular foramen, but in the test group there were differences between two positions of the least moving points during opening and closing. 2. The variations of the least moving point were in the range of $0.02\sim0.05cm$ of X-coordinate and $0.07\sim0.10cm$ of Y-coordinate for control group, whereas in the range of $0.05\sim0.30cm$ of X-coordinate and $0.08\sim1.65cm$ of Y-coordinate for test group. 3. The index of variation during opening and dosing movements was shown in $0.8\sim1.0$ for the control group and in $0.56\sim2.6$ for the test group. 4. After the treatment of the test group No. 4 by occlusal splint the least moving point was dose to the mandibular foramen and the index of variation was changed from 25 to 05. 5. The tracing shape of the least moving point in the test group represented the irregularities compared to the control group. 6. The mandibular opening and dosing movements were simulated on the computer screen following the movement of the least moving point of instantaneous center of rotation.
