Saving power and area with multi-bit pulsed latches
Král, Vojtěch ; Horský, Pavel (referee) ; Dřínovský, Jiří (advisor)
Diplomová práce se zabývá typy výkonových ztrát v technologii CMOS a následně jejich řešením metodami nízké spotřeby, které lze použít v oblasti zákaznických integrovaných obvodů. Jednou z možných metod pro nízkou spotřebu výkonu je vícebitový pulzní klopný obvod, který lze použít jako náhradu za standardní vícebitový klopný obvod typu master-slave. Vícebitový pulzní klopný obvod se skládá ze dvou částí, pulzního generátoru a pulzního klopného obvodu. V diplomové práci jsou popsané topologie, které mohou být použité. Konečná topologie byla vybraná na základě nízké spotřeby a plochy. Z vybrané topologie je vytvořeno schéma vícebitového pulzního klopného obvodu, které je porovnáno se schématem vícebitového klopného obvodu. Následně jsou vytvořeny layouty potřebných vícebitových pulzních klopných obvodů a porovnány jsou se standardními layouty vícebitových klopných obvodů. V závěru práce jsou navrhnuté vícebitové pulzní klopné obvody odsimulovány v jednoduchém designu.

Determining Head Rotation in Video from Security Camera
Blucha, Ondřej ; Drahanský, Martin (referee) ; Goldmann, Tomáš (advisor)
This thesis attempts to create an application to determine head rotation angle in video recorded from a security camera. The application consists of three parts: face detection, facial landmarks detection and determination of person's head rotation. The face detection has been implemented using Viola-Jones and HOG algorithms. Facial landmarks detection has been done using algorithm based on active shape model. Two methods to calculate the head rotation angles have been used: the first method works with anthropometric head features. The second method uses Perspective-n-Point algorithm to find the right rotation angles. Finally, all algorithms implemented have been tested and the proper parameters have been determined.
