چکیده

We examine the relationship between controlled and uncontrolled visual preference tests. We compare the results for the preference of printed images in various viewing environments. The data are examined with regard to different numbers of observer subsets and we can derive an experimental guideline for an equivalence of the controlled and uncontrolled preference experiments based on the certainty of the expected result. © 2010 SPIE and IS&T.

Controlled and uncontrolled viewing conditions in the evaluation of prints

Visual experiments, attesting visual preference, visual ranking and visual differentiation, are very important to academia and industry. They are traditionally performed into laboratories under controlled viewing conditions, resulting very costly in their execution, due to the time and effort involved by all participants. If controlled tests could be substituted by uncontrolled tests, a potenti...

Adapting ISO 20462 Softcopy Quality Ruler Method for on-line Image Quality Studies

The ISO 20462 method for subjective image quality evaluation relies on a set of reference images, which are calibrated in terms of known absolute quality differences. The original reference images, Standard Reference Stimuli (SRS), were in the form of photographic prints, to be viewed under controlled lighting and fixed viewing conditions. This method was then extended for scenes presented on c...

Effect of Gap Acceptance Behavior of the Right Turning Vehicles on the Major Road Stream for Uncontrolled Three-Legged Intersections under Mixed Traffic Conditions

Uncontrolled intersections are the intersections where there are no external signs or signals to control the movement of vehicles. In mixed traffic conditions priority rules are often violated by the road users. In All-way-stop-controlled intersections (AWSC), the vehicle should stop themselves before they enter the intersection and should check whether any vehicles are present in the other app...

Affine Epipolar Direction from Two Views of a Planar Contour

Most approaches to camera motion estimation from image sequences require matching the projections of at least 4 non-coplanar points in the scene. The case of points lying on a plane has only recently been addressed, using mainly projective cameras. We here study what can be recovered from two uncalibrated views of a planar contour under affine viewing conditions. We prove that the affine epipol...
