The goal of this thesis was to develop a web-based tool for object annotation in videos. The tool is designed to provide an interface for annotating objects in order to further use the annotation data in other applications. The tool utilises modern frameworks and libraries for creating user-friendly web applications. This thesis contains information about existing tools, libraries, and tools used in the development process, the user interface development process, and implementation details. The implemented tool includes features for video management, annotation editing, and data import or export. Thanks to the application, the user is able to annotate their videos for further usage in different areas.

Supervisor’s reportIng. Ondřej Klíma, Ph.D.
I rate the work with a grade of B. The result is a functional application tested on real data. However, for use in practice, conducting more extensive user testing and fine-tuning some implementation details would be necessary.
The work was of an implementation nature. The goal was to create an application for annotating extensive videos taken from mobile mapping systems. The purpose was to enable the checking and correction of automatically generated annotations uploaded to the application in their own specific formats. I rate the difficulty of the assignment as average.
The student himself actively found and studied the necessary literature, especially the documentation of existing solutions and available components and tools suitable for creating his own application.
The student was active in the solution and went regularly for consultation, but he did not always keep the consultation deadline. Sometimes, he did not have time to prepare sufficiently for the consultation.
The work was completed on time, and the final content of the work was sufficiently consulted.
I am not familiar with whether the work has been published.
Grade proposed by supervisor: B
Reviewer’s reportIng. David Bařina, Ph.D.
Although one point of the assignment is not fulfilled, I rate the work as successful and comprehensive.
Evaluation level: průměrně obtížné zadání
This is an averagely difficult assignment, but it required the study of many javascript libraries. I particularly appreciate the extensive and clear description of existing tools in chapter 2.
The individual chapters follow each other logically. Although some chapters are shorter, I rate their scope as sufficient. The chapters are easy to understand for the reader.
The typography and language are of a high standard. For the fact that this is a bachelor's thesis, the student uses excellent English.
The program solution is very comprehensive. It is exclusively code in TypeScript (for frontend as well as backend).
The motivation of the work is not clear. Although the student does not indicate for whom he did the work, it is clearly an assignment for a company. It is not clear whether the result of the work was actually used in the company.
Evaluation level: zadání splněno s drobnými výhradami
All but one of the assignment points are completely fulfilled. Evaluation (point 5 of the assignment) is missing. The supervisor claims that the student developed it directly on videos and annotations from Cognitechna company. However, this is not documented in the technical report.
Evaluation level: je v obvyklém rozmezí
The work contains approximately 40 NS without figures. So it is within the usual range.
Student uses footnotes for internet links. Standard citations refer to articles and RFCs accessible primarily online. The number of citations fully corresponds to the solved problem.
