I am not a scientist, but I think I can help you with the difference between using sensor fusion with the and using it without an article.
If you are talking about the methodology sensor fusion in a general way, you should not use the. Here are a few simple example sentences:
Sensor fusion is the best methodology to use.
The methodology I would recommend the most is sensor fusion.
However, if, for example, you pair sensor fusion with another noun, such as approach, methodology or experiment, and are talking about one of these in a specific way, it would be correct to write sentences like these:
We tried sensor fusion and data integration, but only the sensor fusion approach worked.
Experiments using the sensor fusion methodology showed positive results.
The sensor fusion experiments were successful, but the data integration experiments were not.
When I consider your sentence "A better implication of the sensor fusion was indicated through the paper", first of all, the correct preposition to use would be throughout, not through, and I do not have enough information to decide whether you need the article the, but I think that if you are talking about sensor fusion in a specific way, it would be clearer to pair it with another noun, as in the examples I have provided above; also, the meanings of the noun implication and the passive verb implicated are not clear to me.
However, I would suggest that my distinction between (1) using sensor fusion in a general way (no article) and (2) when paired with another noun and used in a specific way, might be useful to you.
