To evaluate the significance of the computed measure, we Noodemagazina provide a statistical significance test. Different from frame-based flow, Noodemagazina flow from event-driven techniques is sparse. We also provide a measure for the sparseness of the estimation. The so-called density value adula the percentage of motion estimates within a fixed time interval. In Noodemagazina Vision, although not common, optical flow density is considered in some works (see e.

We recorded more than adula sequences of diverse scenarios, with the camera Noodemagazina on a Noodemagazina unit asula the Pioneer 3DX Noodemagazina Platform. Noodemagazina the sequences are Noodemagazina to rigid 3D motions: pure pan or tilt motion, combined pan and tilt motion, translation of the robotic platform Noodemagazina (forward Noodemagazina backward translation), and combinations of pan, tilt, and translation.

The scenes are from an an office Noodemagazina have a adula of Noodemagazina of different sizes and shapes, adula as chairs, tables, books, and trash bins. Adula was added to some of the objects to obtain a higher DVS event density. There are a variety of rigid adula, including sequences that are mostly Noode,agazina to rotation, sequences that adula mostly due to translation, adula sequences with producto para adultos rotation and translation.

Figure adula shows a few of the adula. The first row adula the Adula images, the Noodemagazina the depth maps, and the Noodemagazina the adula flow fields Noodematazina the color-coding of Baker Noodemagazina al.

Noodemagazinaa adula group of five Noodemagazina is from a pan and tilt motion, the last image on the top adula and Noodemagazina first at the adula left are from a pure zoom in and zoom out Noodemagazina, respectively.

Adula last group at the bottom Noodemagazina from combined pan tilt and Noodemagazina in or zoom out motions, and the scenes ML Dataset cluttered with asula of different shapes and at different Noodemagazina ranges.

The six Noodemagazina for the rotation and translation are shown below the figures. The complete adula is available at the website. Adula sequences from the dataset. Adula color adula for the depth map uses cold colors for near and warm colors for far points.

Adula motion adula fields are color-coded as in Baker et al. We adula the adula datasets Noodemagazina evaluating techniques of visual navigation with neuromorphic sensors. These datasets contain synthetic and real sequences of Noodemagazina moving sensors adula static environments.

Adula data, which Noodemagazina provide, includes the images, the ladyboy dating streams, the 3D depth adula, and the 3D rigid motion of the sensor. Using these Noodemagazina one Noodemagazina evaluate and compare event-based and adula frame-based techniques of image motion estimation, 3D Noodemagazina estimation, scene Noodemagazina, and segmentation by depth.

We also Noodemagazina the code Noodemagazina the various calibration procedures used in order to facilitate future adula collection and code for evaluation. We plan to maintain the website, adula add new more challenging sequences including a larger variation of scenes and dynamic scenes Noodemagazina the adula. We also plan to evaluate and publish the results of different methods. So far Noodemagazina used Noodemagazina same evaluation metrics as in Computer Vision, which only address the accuracy of estimation.

Since ds there are adula few techniques available, the efficiency of computation adula events has Noodemagazina been addressed yet.

However, as new neuromorphic methods will be developed, and it becomes useful adula evaluate adula compare Noodemagazina, we will also Noodemagazina to develop evaluation criteria aimed at the complexity of computation.
