5. The Impact of Light

Slice ePub May 28, 2014
<p>All vision systems depend on quality images, and quality images in turn depend on light. Because of this, the quality of the light in the vision system environment is a key factor to its success. This chapter takes a deeper look at light and how to use it to illuminate a vision system, including:</p><p>The different types of light sources available</p><p>Ways to evaluate light sources</p><p>Looking at how the target object interacts with light</p><p>Removing unwanted ambient light</p><p>Reviewing different lighting techniques</p><p>Calibrating the camera</p><p>Using color to segment an image</p><p>One of the most common mistakes of beginning computer vision developers is to overlook lighting and its effect on image quality and algorithm performance. Lighting is a critical component in any vision system and can be the difference between success and failure. After all, without lighting, computer vision would be the study of black rooms with black objects. That would actually make vision programming incredibly easy, but not terribly useful. Instead the lighting should help accomplish three main goals:</p><a class="default-logo-link" href="/ebooks/362515-practical-computer-vision-with-simplecv-the-simple-way-to-make-technology-see">See more</a>

<p>As explained in the Introduction, this book has grown in the milieu of lectures, seminars and supervisions, to some extent separated from the clinical work from which theoretical contributions to psycho-analytic literature derive. As a consequence a certain asynchrony is sometimes evident in the text in that reference is made to theoretical ideas which have not as yet taken their place in the literature.</p><p>In the following section these ideas and areas of development will be expanded, as a holding method, until future publications can give them more definition.</p><p>These problems of analytic method and process are of special interest from the structural point of view and will be dealt with extensively by Dr. H. Rosenfeld in a future publication, which will carry forward the work begun in his paper, “An Investigation of the Need of Neurotic and Psychotic Patients to Act Out During Analysis.”<sup></sup>*</p><p>In the text I have referred to a particular aspect of acting-out of transference processes in children, of various ages and how these patterns of acting-out contribute form to their peer-relations and spontaneous group formation.</p><a class="default-logo-link" href="/ebooks/326770-the-psycho-analytical-process">See more</a>
