1. A method comprising:

receiving, at a processor, a set of uncertain characters obtained as a result of a recognition process of a text image, the set of uncertain characters including an image of an uncertain character, a hypothesis about the uncertain character, and a confidence level associated with the hypothesis;

causing, by the processor, a display device to present to a user the image of the uncertain character from the set of uncertain characters over a text readout;

receiving, at the processor from a user input, marking data for the uncertain character; and

adjusting, using the received marking data, the confidence level associated with the hypothesis about the uncertain character for obtaining a confirmed hypothesis linked to the uncertain character.

2. The method of claim 1 , wherein the marking data is one of marked, unmarked or rejected the method further comprising:

in response to determining that the marking data is unmarked for the uncertain character, the processor increasing the confidence level of the hypothesis about the uncertain character;

in response to determining that the marking data is marked for the uncertain character, the processor decreasing the confidence level of the hypothesis about the uncertain character; and

in response to determining that the marking data is rejected for the uncertain character, the processor increasing the confidence level of the hypothesis about the uncertain character.

3. The method of claim 1 , wherein the marking data is one of marked, unmarked, or rejected, the method further comprising:

in response to determining that the marking data is unmarked for the uncertain character, the processor increasing the confidence level of the hypothesis about the uncertain character by a first amount; and

in response to determining that the marking data is rejected for the uncertain character, the processor increasing the confidence level of the hypothesis about the uncertain character by a second amount, wherein the second amount is larger than the first amount.

4. The method of claim 1 , further comprising, determining, prior to causing the image of the uncertain character to be presented, whether the confidence level associated with the hypothesis about the uncertain character is below a predefined non-zero threshold value, wherein the image of the uncertain character is caused to be presented in response to determining that the confidence level of the hypothesis about the uncertain character is below the threshold value.

5. The method of claim 4 , further comprising:

receiving an indication of a desired level of accuracy for recognition of text data; and

adjusting the threshold value in accordance with an indicated desired level of accuracy.

8. The method of claim 1 , wherein the marking data received from a device indicates a number of times that the image of the uncertain character was selected at the device, the method further comprising:

in response to receiving marking data indicating that the image was not selected, the processor designating the marking data for the uncertain character as unmarked;

in response to receiving marking data indicating that the image was selected an odd number of times, the processor designating the marking data for the uncertain character as marked; and

in response to receiving marking data indicating that the image was selected a non-zero even number of times, designating the marking data for the uncertain character as rejected.

9. The method of claim 1 , wherein the image of the uncertain character is inserted in place of a hypothesis character image within a word in the text readout, and wherein the marking data is indicative of whether the word as a whole was marked.

10. The method of claim 1 , wherein the presented image of uncertain character replaces a hypothesis character image within the word.

11. The method of claim 1 , wherein the processor is part of a verification device, facilitating transmission of the adjusted confidence value to a remote server system.

12. The method of claim 1 , further comprising determining whether the confidence level associated with the hypothesis about the uncertain character is resolved as true, resolved as false, or not resolved;

in response to determining that the confidence level associated with the hypothesis about the uncertain character is not resolved, repeating the steps of (a) causing a display device to present the image of the uncertain character over a text readout, (b) receiving marking data for the uncertain character, and (c) adjusting the confidence level associated with the hypothesis about the uncertain character;

in response to determining that the confidence level associated with the hypothesis about the uncertain character is resolved as true, storing verified recognized text; and

in response to determining that the confidence level associated with the hypothesis about the uncertain character is resolved as false, moving to check a next hypothesis about the uncertain character.

13. The method of claim 1 , wherein the processor is part of a display device that is remotely connected to a server system.

14. The method of claim 1 , further comprising: determining font characteristics associated with the image of the uncertain character; and adjusting font characteristics of the text readout in accordance with the determined font characteristics associated with the image of the uncertain character.

15. The method of claim 1 , further comprising determining font characteristics associated with the text readout, wherein the uncertain character is chosen from a set of uncertain characters in accordance with the uncertain character being determined most similar to the determined font characteristics associated with the text readout.

16. A non-transitory computer-readable medium having stored thereon instructions executable by a processor to cause the processor to perform functions, the functions comprising:

causing a display device to present to a user the image of the uncertain character from the set of uncertain characters over a text readout;

receiving from a user input marking data for the uncertain character; and

adjusting, using the received marking data, the confidence level associated with the hypothesis about the uncertain character for obtaining a confirmed hypothesis linked to the uncertain character.

17. The computer-readable medium of claim 16 , wherein the marking data is one of marked, unmarked or rejected the functions further comprising:
